Hi all,
I’m experiencing an interesting issue where I’m attempting to consolidate my snapshots’
backing images on my qemu-kvm install by way of the virsh blockpull and/or virsh
blockcommit commands and receiving the error that my system can not locate the
“block-stream” command. I can’t seem to find much related to this issue by way of my
Google research outside of some Bugzilla posts, which leads me to believe that perhaps
I’ve missed something during my install, maybe there is an ancillary package I need to
install?
I’m running qemu-kvm-0.12.1.2-2.448.el6_6.3.x86_64 with libvirt-0.10.2-29.el6_5.12.x86_64
on CentOS 6.6.
If anyone has experienced this issue before, advise would be greatly appreciated.
Thanks,
Dallas G.

There's your problem. 'qemu-kvm' on CentOS 6 does not support live disk
operations, because it was derived from RHEL 6 where Red Hat did not
choose to backport the functionality unless you upgraded to RHEV.
Quoting from an earlier mail from Paolo Bonzini:
Luckily, since you are using CentOS you do not really care about
official Red Hat RPMs, and you can get the packages here (well, this is
for CentOS 7, I'm not sure if there is a similar repo for CentOS 6):
http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/
This yum repository file will help:
[qemu-kvm-rhev]
name=oVirt rebuilds of qemu-kvm-rhev
baseurl=http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/
mirrorlist=http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-e...
enabled=1
skip_if_unavailable=1
gpgcheck=0
Drop it in /etc/yum.repos.d/qemu-kvm-rhev.repo and install qemu-kvm-rhev
with yum. All features will be available. It would be simpler to have
a CentOS SIG build this, but it hasn't happened yet.

Thanks Eric. Looks like they do have an official 6.6 EL repo which I’ll use.
Thanks,
