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--
# virsh domfsfreeze <domain> --mountpoint <mountpoint>
Output was-- Froze 3 filesystem(s)
I want to freeze a particular mount point on the VM, so that i can

Live snapshot merging (qemu 2.0)
Hello.
The Changelog of qemu-2.0.0 mentioned "Live snapshot merging". Someone
has an idea what could be ment by this? I'm asking because i'm still
struggling with finding a reliable backup solution for running kvm
machines. Blockcopy is my current solution.
best regards

Help with understanding and solving snapshot problem
Hello
Fairly new to libvirt. I’m hoping to both solve a problem with this question as well as learn more detail about how libvirt works.
Using RHEL 6.4 and libvirt version is 0.10.2 and qemu-img version is 0.12.1.2
Using virt-manager I created a VM. Nothing unusual as far as I can see. I then added a disk. So I have a second virtio based volume which the guest then mounts as a separate

After a 'virsh blockpull', 'virsh snapshot-list --tree' o/p does not reflect reality
Hi (Eric?),
A couple of questions while using the 'virsh blockpull'
Summary:
1] Created snapshots this way: base<-snap1<-snap2<-snap3 (online, external snapshot
--disk-only)
2] I did a 'virsh blockpull' from snap2 into snap3
3] Next, did another 'virsh blockpull' from snap1 into snap3
- Here, 'qemu-img info /path/to/snap3' shows its backing file

I’ll try and keep the lines short. I don’t see any obvious setting to change the wrap.

can not lvcreate after lvm snapshot and "xm mem-set" and lvremove
I am not sure if it''s a xen bug or lvm bug, or just my bad hardware,
but here''s how to reproduce:
/dev/vg0/centos1 is lvm block used by a domainU, it''s 8G in size.
#lvcreate -L8192M -s -n snap1 vg0
#mount /dev/vg0/snap1 /mnt
do some copying files here
#umount /mnt
#lvremove /dev/vg0/snap1
not removed! it says can''t allocated memory
#xm mem-set 0 512
#lvremove

[Request for review] [RFC] Add label support for snapshots and subvols
From: Anand Jain <anand.jain@oracle.com>
(This patch is for the review/test not yet for the integration).
Here is an implementation of the feature to add label to the
subvolume and snapshots. Which would help sysadmin to better manager
the subvol and snapshots.
This can be done in two ways, one - using attr which is user land
only changes but drawback is able to change the label

load balancing and DNAT
Does anyone know if load balancing and DNAT work well together? I know
that load balancing and NAT do not, but what about a simple port forward?
I can''t apply Julian Anastasov''s patches, because they don''t work with
PPTP patches. :/
Anyhow, a simple:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport xxx -j DNAT --to

snapshot-current vs snapshot-revert
If I want to go back to a snapshot, what is the difference between

What happens to disk sectors of the current state when reverting to

Changing 'source file' on running VM.
So I notice that some operations by libvirt such as creating a snapshot actually change the source of the active disk image for a domain without requiring a restart of the vm. How can this be achieved manually? There are instances where I am manipulating files with qemu-img or virsh commands and afterward need to change what file the vm is using as its disk. One example is when deleting a
