KVM Failure (10)-Various minor surprises

the amount ..... Write to which is where, a lot of understanding!!!!

1. Yesterday the server unexpectedly power off, the results of one of the KVM virtual machine is not up, error
"Error restoring domain:operation failed:failed to read QEMU header"

At first, a new virtual machine, and then put the hard disk on, start, normal start, but the original configuration is not, this means that the virtual disk is not a problem, or think about the perfect recovery, to Google search, found that the original main machine in the process of the current KVM state, and the next start to recover, The virtual state file is saved in/var/lib/libvirt/qemu/save, it should be accidental power loss caused the virtual state file is missing, unable to read and resume normally, the workaround is to delete the virtual state file.

Command:
rm-rf/var/lib/libvirt/qemu/save/(virtual machine name). Save

Then reboot, normal, problem solved.

2.error:usbdevicelistadd:425:internal Error Device 001:003 is already on use

Solution: After removing the USB two hardware, reboot

3. On the Mac SSH remote operation redhat6.2 above the Virt-manager management virtual machine! The result is the following error!

fsxchen:~ apple$ ssh-x [email protected] Virt-manager
Traceback (most recent):
File "/usr/share/virt-manager/virt-manager.py", line 383, in <module>
Main ()
File "/usr/share/virt-manager/virt-manager.py", line 248, in main
cli.setup_i18n (Gettext_app, Gettext_dir)
File "/usr/share/virt-manager/virtmanager/cli.py", line +, in setup_i18n
Locale.setlocale (locale. Lc_all, ")
File "/usr/lib64/python2.6/locale.py", line 513, in setlocale
Return _setlocale (category, Locale)
Locale. error:unsupported locale Setting

Workaround:

Export Lc_all=en_us. UTF-8

Reason: KVM can only use English mode
