This chapter covers common problems and solutions for Red Hat Enterprise Linux 6 virtualization issues.
Read this chapter to develop an understanding of some of the common problems associated with virtualization technologies. Troubleshooting takes practice and experience which are difficult to learn from a book. It is recommended that you experiment and test virtualization on Red Hat Enterprise Linux 6 to develop your troubleshooting skills.
If you cannot find the answer in this document there may be an answer online from the virtualization community. Refer to Section A.1, "Online resources" for a list of Linux virtualization websites.

19.1. Debugging and troubleshooting tools

This section summarizes the System Administrator applications, the networking utilities, and debugging tools. You can employ these standard System administration tools and logs to assist with troubleshooting:
  • kvm_stat
  • trace-cmd
  • vmstat
  • iostat
  • lsof
  • systemtap
  • crash
  • sysrq
  • sysrq t
  • sysrq w
These networking tools can assist with troubleshooting virtualization networking problems:
  • ifconfig
  • tcpdump
    The tcpdump command 'sniffs' network packets. tcpdump is useful for finding network abnormalities and problems with network authentication. There is a graphical version of tcpdump named wireshark.
  • brctl
    brctl is a networking tool that inspects and configures the Ethernet bridge configuration in the Linux kernel. You must have root access before performing these example commands:
    # brctl show bridge-name bridge-id  STP  enabled  interfaces  -----------------------------------------------------------------------------virtbr0 8000.feffffff   yes eth0# brctl showmacs virtbr0 port-no   mac-addr  local?   aging timer1 fe:ff:ff:ff:ff:   yes 0.002 fe:ff:ff:fe:ff:   yes 0.00# brctl showstp virtbr0virtbr0 bridge-id  8000.fefffffffffdesignated-root 8000.fefffffffffroot-port  0   path-cost 0max-age 20.00   bridge-max-age 20.00hello-time 2.00 bridge-hello-time 2.00forward-delay  0.00 bridge-forward-delay  0.00aging-time 300.01hello-timer 1.43 tcn-timer 0.00topology-change-timer  0.00 gc-timer  0.02
Listed below are some other useful commands for troubleshooting virtualization.
  • strace is a command which traces system calls and events received and used by another process.
  • vncviewer: connect to a VNC server running on your server or a virtual machine. Install vncviwer using the yum install vnc command.
  • vncserver: start a remote desktop on your server. Gives you the ability to run graphical user interfaces such as virt-manager via a remote session. Install vncserver using the yum install vnc-server command.

19.2. kvm_stat

The kvm_stat command is a python script which retrieves runtime statistics from the kvm kernel module. The kvm_stat command can be used to diagnose guest behavior visible to kvm. In particular, performance related issues with guests. Currently, the reported statistics are for the entire system; the behavior of all running guests is reported.
The kvm_stat command requires that the kvm kernel module is loaded and debugfs is mounted. If either of these features are not enabled, the command will output the required steps to enable debugfs or the kvm module. For example:
# kvm_statPlease mount debugfs ('mount -t debugfs debugfs /sys/kernel/debug')and ensure the kvm modules are loaded
Mount debugfs if required:
# mount -t debugfs debugfs /sys/kernel/debug
kvm_stat output
The kvm_stat command outputs statistics for all guests and the host. The output is updated until the command is terminated (using Ctrl+c or the q key).

Note

The output information from the kvm_stat command is exported by the KVM hypervisor as pseudo files located in the /sys/kernel/debug/kvm/ directory.

19.3. Troubleshooting with serial consoles

Linux kernels can output information to serial ports. This is useful for debugging kernel panics and hardware issues with video devices or headless servers. The subsections in this section cover setting up serial console output for machines running Red Hat Enterprise Linux 6 virtualization kernels and their guests.
This section covers how to enable serial console output for fully virtualized guests.
Fully virtualized guest serial console output can be viewed with the virsh console command.
Be aware fully virtualized guest serial consoles have some limitations. Present limitations include:
  • output data may be dropped or scrambled.
The serial port is called ttyS0 on Linux or COM1 on Windows.
You must configure the virtualized operating system to output information to the virtual serial port.
To output kernel information from a fully virtualized Linux guest into the domain, modify the /boot/grub/grub.conf file. Append the following to the kernel line: console=tty0 console=ttyS0,115200.
title Red Hat Enterprise Linux Server (2.6.32-36.x86-64)root (hd0,0)kernel /vmlinuz-2.6.32-36.x86-64 ro root=/dev/volgroup00/logvol00 \ console=tty0 console=ttyS0,115200initrd /initrd-2.6.32-36.x86-64.img
Reboot the guest.
On the host, access the serial console with the following command:
# virsh console
You can also use virt-manager to display the virtual text console. In the guest console window, select Serial 1 in Text Consoles from the View menu.

19.4. Virtualization log files

  • Each fully virtualized guest log is in the /var/log/libvirt/qemu/ directory. Each guest log is named as GuestName.log and will be periodically compressed once a size limit is reached.
If you encounter any errors with the Virtual Machine Manager, you can review the generated data in the virt-manager.log file that resides in the $HOME/.virt-manager directory.

19.5. Loop device errors

If file-based guest images are used you may have to increase the number of configured loop devices. The default configuration allows up to eight active loop devices. If more than eight file-based guests or loop devices are needed the number of loop devices configured can be adjusted in the /etc/modprobe.d/directory. Add the following line:
options loop max_loop=64
This example uses 64 but you can specify another number to set the maximum loop value. You may also have to implement loop device backed guests on your system. To use a loop device backed guests for a full virtualized system, use the phy: device or file: file commands.

19.6. Live Migration Errors

There may be cases where a live migration causes the memory contents to be re-transfered over and over again. This process causes the guest to be in a state where it is constantly writing to memory and therefore will slow down migration. If this should occur, and the guest is writing more than several tens of MBs per second, then live migration may fail to finish (converge). This issue is not scheduled to be resolved at the moment for Red Hat Enterprise Linux 6, and is scheduled to be fixed in Red Hat Enterprise Linux 7.
The current live-migration implementation has a default migration time configured to 30ms. This value determines the guest pause time at the end of the migration in order to transfer the leftovers. Higher values increase the odds that live migration will converge

19.7. Enabling Intel VT-x and AMD-V virtualization hardware extensions in BIOS

This section describes how to identify hardware virtualization extensions and enable them in your BIOS if they are disabled.
The Intel VT-x extensions can be disabled in the BIOS. Certain laptop vendors have disabled the Intel VT-x extensions by default in their CPUs.
The virtualization extensions cannot be disabled in the BIOS for AMD-V.
Refer to the following section for instructions on enabling disabled virtualization extensions.
Verify the virtualization extensions are enabled in BIOS. The BIOS settings for Intel VT or AMD-V are usually in the Chipset or Processor menus. The menu names may vary from this guide, the virtualization extension settings may be found in Security Settings or other non standard menu names.

Procedure 19.1. Enabling virtualization extensions in BIOS

  1. Reboot the computer and open the system's BIOS menu. This can usually be done by pressing the delete key, the F1 key or Alt and F4 keys depending on the system.

  2. Enabling the virtualization extensions in BIOS

    Note

    Many of the steps below may vary depending on your motherboard, processor type, chipset and OEM. Refer to your system's accompanying documentation for the correct information on configuring your system.
    1. Open the Processor submenu The processor settings menu may be hidden in the Chipset, Advanced CPU Configuration or Northbridge.
    2. Enable Intel Virtualization Technology (also known as Intel VT-x). AMD-V extensions cannot be disabled in the BIOS and should already be enabled. The virtualization extensions may be labeled Virtualization Extensions, Vanderpool or various other names depending on the OEM and system BIOS.
    3. Enable Intel VT-d or AMD IOMMU, if the options are available. Intel VT-d and AMD IOMMU are used for PCI device assignment.
    4. Select Save & Exit.
  3. Reboot the machine.
  4. When the machine has booted, run cat /proc/cpuinfo |grep -E "vmx|svm". Specifying --color is optional, but useful if you want the search term highlighted. If the command outputs, the virtualization extensions are now enabled. If there is no output your system may not have the virtualization extensions or the correct BIOS setting enabled.

19.8. KVM networking performance

By default, KVM virtual machines are assigned a virtual Realtek 8139 (rtl8139) NIC (network interface controller) if they are Windows guests or the guest type is not specified. Red Hat Enterprise Linux guests are assigned a virtio NIC by default.
The rtl8139 virtualized NIC works fine in most environments. However, this device can suffer from performance degradation problems on some networks, for example, a 10 Gigabit Ethernet network.
To improve performance switch to the para-virtualized network driver.

Note

Note that the virtualized Intel PRO/1000 (e1000) driver is also supported as an emulated driver choice. To use the e1000 driver, replace virtio in the procedure below with e1000. For the best performance it is recommended to use the virtio driver.

Procedure 19.2. Switching to the virtio driver

  1. Shutdown the guest operating system.
  2. Edit the guest's configuration file with the virsh command (where GUEST is the guest's name):
    # virsh edit GUEST
    The virsh edit command uses the $EDITOR shell variable to determine which editor to use.
  3. Find the network interface section of the configuration. This section resembles the snippet below:
    <interface type='network'>  [output truncated]  <model type='rtl8139' /></interface>
  4. Change the type attribute of the model element from 'rtl8139' to 'virtio'. This will change the driver from the rtl8139 driver to the e1000 driver.
    <interface type='network'>  [output truncated]  <model type='virtio' /></interface>
  5. Save the changes and exit the text editor
  6. Restart the guest operating system.
Creating new guests using other network drivers
Alternatively, new guests can be created with a different network driver. This may be required if you are having difficulty installing guests over a network connection. This method requires you to have at least one guest already created (possibly installed from CD or DVD) to use as a template.
  1. Create an XML template from an existing guest (in this example, named Guest1):
    # virsh dumpxml Guest1 > /tmp/guest-template.xml
  2. Copy and edit the XML file and update the unique fields: virtual machine name, UUID, disk image, MAC address, and any other unique parameters. Note that you can delete the UUID and MAC address lines and virsh will generate a UUID and MAC address.
    # cp /tmp/guest-template.xml /tmp/new-guest.xml# vi /tmp/new-guest.xml
    Add the model line in the network interface section:
     <interface type='network'>  [output truncated]  <model type='virtio' /></interface>
  3. Create the new virtual machine:
    # virsh define /tmp/new-guest.xml# virsh start new-guest

19.9. Missing characters on guest console with Japanese keyboard

On a Red Hat Enterprise Linux 6 host, connecting a Japanese keyboard locally to a machine may result in typed characters such as the underscore (the _ character) not being displayed correctly in guest consoles. This occurs because the required keymap is not set correctly by default.
With Red Hat Enterprise Linux 3 and Red Hat Enterprise Linux 6 guests, there is usually no error message produced when pressing the associated key. However, Red Hat Enterprise Linux 4 and Red Hat Enterprise Linux 5 guests may display an error similar to the following:
atkdb.c: Unknown key pressed (translated set 2, code 0x0 on isa0060/serio0). atkbd.c: Use 'setkeycodes 00 <keycode>' to make it known.
To fix this issue in virt-manager, perform the following steps:
  • Open the affected guest in virt-manager.
  • Click View ⤍ Details.
  • Select Display VNC in the list.
  • Change Auto to ja in the Keymap pull-down menu.
  • Click the Apply button.
Alternatively, to fix this issue using the virsh edit command on the target guest:
  • Run virsh edit <target guest>
  • Add the following attribute to the <graphics> tag: keymap='ja'. For example: 
     <graphics type='vnc' port='-1' autoport='yes' keymap='ja'/>

19.10. Known Windows XP guest issues

If you perform device-add quickly followed by device-del using a Windows XP guest, the guest does not eject the device and instead it displays the following error: "The device (device name) cannot be stopped because of an unknown error. Since the device is still being used, do not remove it". It should be noted that newer Windows OS version guests as well as all known Linux guests do not experience this problem. To prevent this issue from happening, wait to delete a device that you just added.
