[Qemu-discuss] Freeze Windows Guests For Consistent Storage Snapshots

[Payes Anand]

Hi,

Is it possible to freeze windows guests for a consistent storage level snapshot.

I am using openstack icehouse on centos 6.6

Hypervisor: KVM

Libvirt: 0.10.2

Qemu: 0.10.2

Guest OS: Windows 7 and Windows Server 2008

I was able to freeze Centos guests by issuing the  command:

virsh qemu-agent-command <guest_ID> '{"execute":"guest-fsfreeze-freeze"}'

For CentOS guests, I enabled access between compute nodes and guests through a socket by setting metadata parameter, hw_qemu_guest_agent=yes for the guest image.

And then installing qemu-guest-agent inside the guest.

What steps do i have to follow for windows ?

Regars,

Payes
