[libvirt] [PATCH] qemu: Introduce qemuDomainDelChardevTLSObjects
by John Ferlan 21 Dec '17

21 Dec '17

Let's make a comment deletion helper similar to the Add helper that can be called after the ExitMonitor. The modify qemuDomainRemoveChrDevice and qemuDomainRemoveRNGDevice to call the helper instead of inlining the copy and pasted code. Signed-off-by: John Ferlan <jferlan(a)redhat.com> --- An offshoot of the redirdev hot unplug patches from Chen Hanxiao.

[libvirt] Executing gdb/gcore as an on_crash action
by Sergio Lopez 21 Dec '17

21 Dec '17

Hi, Right now, the actions coredump-[destroy|restart] for on_crash work in a similar way as "virsh dump", requesting a dump of Guest's memory contents to QEMU. I think it'd be nice to have the ability for executing gdb/gcore to produce a full core dump of QEMU. This would be especially useful for debugging hard/soft lockups on the Guest. Of course, this should be implemented in a completely optional way, checking if the gdb binary is present, to avoid creating a direct dependency between libvirt and gdb. I'm willing to work on a patch implementing this feature myself, but first I'd like to know if this sounds good to you. Also, if it does, do you think the behavior of coredump-[destroy|restart] should be changed to use gdb if available, falling back to qemuDomainCoreDump if it isn't, or just implement another action for on_crash? -- Sergio

[libvirt] [PATCH] virt-aa-helper: handle more disk images

[libvirt] RFC: Introduce a dlm-corosync for Lock manager plugin
by Fu.Lin 20 Dec '17

20 Dec '17

Hi, Currently the lock manager infrastructure has implementation of nop, sanlock and lockd. The first do nothing, while sanlock and lockd all requires the share stroage, and lockd is not provided fence mechanism, sanlock would force to restart OS when stopping daemon. The first half of 2017, QEMU introduced the `share-rw` and `file.locking` to handle a problem: https://bugzilla.redhat.com/show_bug.cgi?id=1080152 , someone said: There is also scope for creating new plugins for libvirt to use other mechanism if someone comes up with other ideas. So what about dlm-corosync? DLM(distributed lock manage) is implemented by kernel, it provides some userspace API by "libdlm" to lock/unlock resource, using these API need a daemon named dlm_controld. "Corosync" is cluster messager layer using TCP or UDP, responsible for members management in cluster. dlm_controld and corosync are formed a kind of lock which could be used in cluster. And there is another component named "sbd" providing fence mechanism, it's not necessary, `dlm_controld -f 0` would disable it. As for implement, I think we could make use of virtlockd daemon, just add some RPC callback in micro-on. -- Regards River
