[libvirt-users] Automated hashdeep and upgrade for VMs
by Sean Alexandre
Are there any utilities or scripts that automate the process of upgrading VMs,
along with other maintenance such as doing a hashdeep check of system files?
The key features I'm looking for would do something like:
- A: Shut down VM.
- B: Do a hashdeep check of system files.
- C: Optionally restore VM from a previous backup.
- D: Restart VM.
- E: Upgrade packages.
- F: Shut down VM.
- G: Backup VM (for next "C".)
- H: Run hashdeep on system files (for next "B".)
- I: Restart VM.
Other features, but less important, would backup/restore application files as
well.

Re: [libvirt-users] kvm/libvirt can't use vmdk files? qemu: 'vmdk' invalid format
by Hammad Siddiqi
Dear All,
While trying to run kvm VM using vmdk disk on 6.4 , I got into the
following error,
error: Failed to create domain from vmdkvm.xml
error: internal error process exited while connecting to monitor: qemu-kvm:
-drive
file=/mnt/vmdkTOKVM/vmdkTOKVM.vmdk,if=none,id=drive-ide0-0-0,format=vmdk,cache=none:
'vmdk' invalid format
upon further digging I came across this thread (
https://www.redhat.com/archives/libvirt-users/2011-November/msg00044.html)
also qemu-kvm shows that vmdk is supported but all in vain
Even if I try running with command line instead of XML I get error though
it says it is supported
[root@vmdkTOKVM]# /usr/libexec/qemu-kvm -drive
file=/mnt/vmdkTOKVM/vmdkTOKVM.vmdk,format=?
Supported formats: raw cow qcow vdi vmdk cloop dmg bochs vpc vvfat qcow2
qed parallels nbd blkdebug host_cdrom host_floppy host_device file
[root@vmdkTOKVM]# /usr/libexec/qemu-kvm -drive
file=/mnt/vmdkTOKVM/vmdkTOKVM.vmdk,format=vmdk
qemu-kvm: -drive file=/mnt/XOcom-prx-kvm/XOcom-prx-kvm.vmdk,format=vmdk:
'vmdk' invalid format
The packages being used are:
qemu-img-0.12.1.2-2.355.0.1.el6_4.9.x86_64
qemu-kvm-0.12.1.2-2.355.0.1.el6_4.9.x86_64
qemu-kvm-tools-0.12.1.2-2.355.0.1.el6_4.9.x86_64
libvirt-0.10.2-18.el6_4.14.x86_64
Any help in this regard will highly be apprectiated.
Thank you

[libvirt-users] Exploring linbvirt.
by cooldharma06
hi,
i am started to exploring libvirt. i am using the version libvirt-1.1.3 and
i want to know (or) find the path how the libvirt is creating VM with xen
(libxl) in the source. Any guide or reference is available for this. How i
can find the path of calling sequence for other operations(api). Guide me
to get some idea on debugging the libvirt.

[libvirt-users] help with VM migration problem: getfd, SCM_RIGHTS
by Joe Linoff
Hi,
I am getting the following error when I try to migrate two VM's on my network using virt-manager:
Unable to migrate guest: internal error unable to execute QEMU command 'getfd': No file descriptor supplied via SCM_RIGHTS
All of the other VM's work just fine. There are 18 and I tested all of them.
Version info
OS: CentOS 6.4 (2.6.32-358.23.2) [the hypervisors and the guests]
Compiled against library: libvirt 0.10.2
Using library: libvirt 0.10.2
Using API: QEMU 0.10.2
Running hypervisor: QEMU 0.12.1
It looks like this might be related to bug 731243 in the red hat bug DB but that was for 0.9.4.
If it is related to SELinux permissions, where can I look to fix it?
I ran "sealert -a /var/log/audit/audit.log" on the source hypervisor, the destination hypervisor and on the VM itself but no alerts were reported.
Any hints would be greatly appreciated, I am not sure what to try next.
Thanks,
Joe

Re: [libvirt-users] migrate & virtlockd

Any ideas ?

Objet : migrate & virtlockd
Hi all,
I'm testing virtlockd with libvirt 1.1.3 and it seems I can't migrate my VMs from the first to my second kvm node (on a NFS storage). Virtlockd is locking my qcow2 :
Error : resource busy Lockspace resource 'ea3jkj78.....' is locked
As a result my VM is paused.
How can I fix this behavior ?
Thank you for your help.
