Fixed In Version: vt13.12
Doc Type: Known Issue
Doc Text:
Libvirt 1.2.8 introduced a regression where disk type is converted from "block" to "file" after live storage migration. This breaks the disk extension logic, leading to unwanted extension using all free space in the storage domain. libvirt-daemon-1.2.8-16.el7_1.1 and libvirt-python-1.2.8-6.el7_1.1 fixed this issue by adding a new flag. RHEV-3.5.0-2 is using the new flag when available, fixing this issue. However, the fix in RHEV-3.5.0-2 is effective only when using fixed versions of libvirt-daemon and libvirt-python. Do not perform live storage migration on block storage in RHEL 7.1 unless unless you have the fixed version of libvirt-daemon (libvirt-daemon-1.2.8-16.el7_1.1) and libvirt-python (libvirt-python-1.2.8-6.el7_1.1). These versions should be available as a zero-day async release with RHEL 7.1.

This clone is to tack the async 3.5.0-2 fix.

Live storage migration during IO to the VM disk is finished without extra lvextend calls.

Tested using the following:
rhev 3.5.0-2 - vt13.12
RHEVM - 3.5.0-0.33.el6ev
RHEL 7.1
vdsm-4.16.8.1-7.el7ev.x86_64
libvirt-daemon-1.2.8-16.el7_1.1.x86_64
libvirt-client-1.2.8-16.el7_1.1.x86_64
libvirt-python-1.2.8-7.el7_1.1.x86_64

Tested also with RHEL6.6 and RHEL7.0 hosts.
