Change in vdsm[master]: dump the core of a domain

ShaoHe Feng has uploaded a new change for review. Change subject: dump the core of a domain ...................................................................... dump the core of a domain libvirt support an API to dump the core of a domain on a given file for analysis when guest OS crash. There are two kind of dump files. one is QEMU suspend to disk image. the other is core file which like kdump file butcontains registers' value. It's helpful to support by VDSM to find root cause if a guest gets hang and kdump isn't set up in it. This would be a good RAS feature. Here's the definition of the new API: coreDump: This method will dump the core of a domain on a given file for analysis. Input parameter: vmId - VM UUID to - the core file named by the user flags - defined in libvirt.py VIR_DUMP_CRASH VIR_DUMP_LIVE VIR_DUMP_BYPASS_CACHE VIR_DUMP_RESET VIR_DUMP_MEMORY_ONLY Return value: success: return doneCode failure: return errCode including underlying libvirt error message.

19 Oct '15

Hello Ayal Baron, Bala.FA, Saggi Mizrahi, Dan Kenigsberg, I'd like you to do a code review. Please visit http://gerrit.ovirt.org/18355 to review the following change. Change subject: gluster: Setup and verify ssl connection between nodes. ...................................................................... gluster: Setup and verify ssl connection between nodes. This will be used in geo-replication session creation. Because, there should be password-less ssh access between at least one node of master volume and one node of slave volume before creating geo-replication session. Below new verbs are added *glusterValidateSshConnection *glusterSetupSshConnection Change-Id: Ia6f040b1343998de4f8e28419c63e380240368db Signed-off-by: Bala.FA <barumuga(a)redhat.com> Signed-off-by:

Change in vdsm[master]: vm: Modify and save state after hotunplugging the disk
by xfrancis＠redhat.com 11 Oct '15

11 Oct '15

Xavi Francisco has uploaded a new change for review. Change subject: vm: Modify and save state after hotunplugging the disk ...................................................................... vm: Modify and save state after hotunplugging the disk The rationale behind this patch is to modify the way the hotunplug process is executed. Now when the hotunplug command is called we first remove the disk from the internal state and after that the libvirt hotunplug command is executed.The problem with that approach is that if VDSM restarts between the modification of the internal state and the actual unplugging of the disk, the disk never gets unplugged leaving the system in an inconsistent state. This patch solves the issue by executing the modification of the internal state after the actual unplugging has successfully happened. This state is later saved so if either the disk has been unplugged or not VDSM is able to recover its state in case of a restart.
