Looks like blockpull does not accept a subset of the entire chain of backing files
Hello
If I'm not terribly mistaken, looks like libvirt 1.2.1 does not provide
ability of merging only a subset of the entire chain of backing files.
So, if I have a chain like this:
root <- a <-b <- c <- d <- active
... and I'd like to obtain a chain like this:
root <- c <- d <- active
... looks like it's not supported,

Re: VM I/O performance drops dramatically during storage migration with drive-mirror

I haven't done any v2v conversions in L2 (or at any other level).

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.

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:

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: Double fault panic in L2 upon v2v conversion
Hi,
We all agree that it's not specific to virt-v2v.
I managed to reproduce the same double fault on "normal" L2 boot - without
libguestfs interference.
And as Paolo wrote already, he will take a look at it.
Thanks,
Rom
