RE: guest-fsfreeze-freeze freezes all mounted block devices
Hi Peter,
Should I assume that the virsh domfsfreeze, does not require the
qemu-agent service in the guest?
PS. I couldn't find the result. Afaik it looks like it is returning the
amount of frozen/thawed filesystem's

No. That's the official way how to drive the "guest-fsfreeze-freeze"
agent command via libvirt, thus you must have the guest agent the same
way as you used it before.
Using qemu-agent-command is a backdoor for testing arb...

Issue with fsfreeze with qemu agent.
...frees the guest file system with the qemu guest agent.
With the exeption of one guest, this procedure works fine. On the 'unwilling' guest, I get this error message:
"ERROR 2016-05-25 00:51:19 | T25-bakVMSCmsrvVH2 | fout: internal error: unable to execute QEMU agent command 'guest-fsfreeze-freeze': failed to freeze /: Device or resource busy"
I don't think this is not some sort of time-out error, because activation of the fsfreeze and the error message happen immediately after each other:

guest-fsfreeze-freeze freezes all mounted block devices
I wondered if anyone here can confirm that
virsh qemu-agent-command domain '{"execute":"guest-fsfreeze-freeze"}'
Freezes all mounted block devices filesystems. So if I use 4 block
devices they are all frozen for snapshotting. Or just the root fs?

After a little bit of fiddling i've got this running. Here is what's
neccessary in case someone wanna try this too.
qemu-guest.-agent has to run with the option: "-F /etc/qemu/fsfreeze-hook".

Sadly, it didn't spell out the name of where you install hook scripts
into the guest. But this commit is pretty telling:

Note that libvirt implements this directly via 'virsh domfsfreeze'. This
is the corresponding man page entry:

Freeze Windows Guests For Consistent Storage Snapshots
...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 ?

[PATCH 3/4] fsfreeze: manage kill signal when sb_start_pagefault is called
In every place where sb_start_pagefault was called now we must manage
the error code and return VM_FAULT_RETRY.

Problem with the use of domfsfreeze mountpoint option
Hi everybody,
I am having a problem with the use of domfsfreeze command.
It is freezing all the filesystems present on the domain,
instead of freezing just the mountpoints provided.
I am issuing the command--

Output was-- Froze 3 filesystem(s)

I managed to update to libvirt 1.2.11. Guest Agent is running in the vm.
I'm trying to snapshot:
virsh # snapshot-create-as --domain sles11 --name sn_sles11 --atomic
--disk-only --quiesce
error: internal error: unable to execute QEMU agent command
'guest-fsfreeze-freeze': The command guest-fsfreeze-freeze has been
disabled for this instance
What is now going on ?
Guest Agent in VM is qemu-guest-agent-2.0.2-1.35.

backup-begin
Hello,
For some vms the virsh backup-begin sometimes shuts off the vm and
returns "error: operation failed: domain is not running" although it was
clearly in state running (or paused).
Is the idea that you should guest-fsfreeze-freeze / virsh suspend before
virsh backup-begin? I have tried with both with the same results.
What could be causing the machine to shut off?
Thanks,
Andr?
