[ppc64le] VM crashes if guest kernel is old
Last modified: 2016-06-30 02:39:46 EDT
Description of problem:
For guest running on ppc64 host, VM crashes if kernel version is older than
kernel-3.10.0-327.2.1.el7, or if host kernel is older that this version.
This should be documented.
Version-Release number of selected component (if applicable):
engine: rhevm 3.6.1-4
host: rhel 7.2 for ppc
it's important to note that this is only due to hotplug actions. Without hotplug attempts the system is running fine. We should advise that older OS releases should avoid such actions
Ilanit, can you please test any of those failing/crashing hotplugs on RHEL 6(I guess 6.7) and 7.1? We claimed support....so if it's crashing we have to push a fix to kernel zstreams and document it nevertheless
The following guests were tested on PPC environment, with rhel 7.2 host, with kernel 3.10.0-327.2.1.el7.ppc64le:
RHEL-7.1-20150219.1-Server-ppc64 kernel 3.10.0-229.el7.ppc64
RHEL-6.7-20150429.0-Server-ppc64 kernel 2.6.32-554.el6.ppc64
RHEL-LE-7.1-20150219.1-Server-ppc64le kernel 3.10.0-229.ae17b.ppc64le
For all guests the hot plug flow from BZ 1292441 (Vnic hot unlug/plug) was run 10 times, and worked OK: no VM crash was seen.
Does this bug still need to be documented as a known issue in the Release Notes? Comment #4 suggests that the bug was fixed. Can you please confirm?
In reply to comment #5:
Yes. It needs to be documented.
This bug is not resolved, and not planned to be resolved.
This bug was reported for a guest of rhel 7.2, and kernel version is OLDER than
Comment #4, just adds some information:
On guests of rhel 7.1/rhel6.7, this problem was not seen (so only rhel 7.2 guest).
This bug was added as a known issue in the RHEV 3.6 Release Notes:
