P2P live migration with non-shared storage: fails to connect to remote libvirt URI qemu+ssh
Migration without --p2p works just fine, ie. the below works:
$ virsh migrate --verbose --copy-storage-all \
--live cvm1 qemu+ssh://kashyapc@devstack3/system
Migration: [100 %]
Result:
- On the source host, the guest is shut off
- On the destination host, the guest is live migratied successfully
Migration with "--p2p" fails, a simple test below:

preallocation=full Vs preallocation=metadata
Hi All
I was reading through this:
http://kashyapc.com/2011/12/02/little-more-disk-io-perf-improvement-with-fallocateing-a-qcow2-disk/
I was basically searching for pointers on improving disk I/O.
I wanted to know the purpose of preallocation=full &
preallocation=metadata , What is the difference between them ? and which
one would yield a better disk I/O speed ?
Appreciate your

Re: Efficient live disk backup with active blockcommit : Failed 'block-commit': Could not reopen file: Permission denied
Thanks Kashyap for replying.
QEMU has permissions to the directory which is having images. I will look
into the AppArmor issue and find out more about this.
Also as per suggestion from the link i have uncommented the user and group
from the qemu.conf file - https://github.com/jedi4ever/veewee/issues/996
By checking more on the AppArmor and sVirt issue , i have modified the

Re: Efficient live disk backup with active blockcommit : Failed 'block-commit': Could not reopen file: Permission denied
This is not a libvirt/redhat question…
With your method you can only revert to versions which are available in the standard repositories. You’ll have to download the packages manually to force a different version. Use with caution. There is a reason why the version isn’t in the standard repositories.

Migrating guests
Hi,
I'm experimenting with the migration function of virsh. I'm doing the migrate with following commands:
virsh migrate --life --persistent --copy-storage-all --verbose --abort-on-error domain qemu+ssh://root@destination/system
virsh migrate-setmaxdowntime domain 20000
However sometimes at the end of the migration, the guest isn't started on the destination host. So I'm left
