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

by shaohef＠linux.vnet.ibm.com

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.

Change in vdsm[master]: gluster: Setup and verify ssl connection between nodes.

by tjeyasin＠redhat.com

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:
