Re: internal snapshot question
hi Martin,
thanks again for the feedback. maybe you have noted that I am not yet all too familiar with those tools.
this is now sort of working for me. But I sense that you seem this method to be less then ideal.
Reading through the virsh manual it looks like ...
$ virsh snapshot-create [domain] --disk-only --live
... might be doing a similar thing. Maybe more elegant (pure virsh) and on a

Re: internal snapshot question
tried it (--live wasn't accepted, so I shut the VM down) and produced a snapshot
$ sudo virsh snapshot-delete [domain] [sn-id]
returns an error though
>> error: Failed to delete snapshot [sn-id]
>> error: unsupported configuration: deletion of 1 external disk snapshots not supported yet
so do I have to look into the block commit area to proceed here?

KVM incremental backup using CBT
Hi
Looking in to implementing (CBT like) delta backup for KVM.
The following looks promising..(last paragraph)

disk using dirty-bitmap as reference. How to accomplish this ?
block-mirror with bitmap or is there a qemu-img command ? some details

Ubuntu 14.04 virsh 1.2.2 blockcommit hangs at 100% / command 'blockcommit' doesn't support option --pivot
Hello All,
I think I have seen this in previous bugs. Trying to live backup qcow2
images. I am able to virsh snapshot-create-as and virsh domblklist shows
correct new source, but I am unable to commit back changes to qcow base. I
get the above error.

Qemu is (2.0.0+dfsg-2ubuntu1.22)
I tried compiling latest libvirt, but cannot get it to connect to socket on

virsh create snapshot not honoring diskspec?
Hi,
I'm trying to create a snapshot on a specific disk by using diskspec
option. However, libvirt/virsh seems to ignore it and takes a snapshot of
all disks. Am I using this option incorrectly?
In below examples, I'm trying to snapshot only vdb. However even vda is
getting snapshotted regardless of diskspec. Is this a known issue?
I'm on CentOS 7.1, libvirtd (libvirt) 1.2.8, virsh

recovering from deleted snapshot
I have an automatic process setup. It's still pretty new and obviously
in need of better error handling because now I find myself in a bad state.
I run snapshot-create-as across all my vms, then do zfs replication to
the target backup system, then blockcommit everything.
virsh snapshot-create-as --domain $vm snap --diskspec
$DISK,file=$VMPREFIX/"$vm"-snap.qcow2 --disk-only --atomic

The below does not seem like snapshots. They're *internal* qcow2
snapshots (original and delta are on the same file).

[OT] Apache rewrite stuff...
Hi all, a little off topic, but was wondering what the best way is to
re-write incoming requests so that they all end up at the same domain.
For example, if I had:
my_domain.net
my_domain.com
my_domain.org
Whats the best way to map/redirect all of these to
www.my_domain.com
?
I know its possible, just not sure what to add for rules/virtual hosts
in my apache config.
Thanks for the help!
