Description

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. Hi Ilanit, 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? Kind Regards, Lucy 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 kernel-3.10.0-327.2.1.el7. 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: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html-single/Release_Notes/index.html#Known_Issues Closing. |
