[libvirt] [PATCHv4 0/2] Added waiting for DAD to finish for bridge address.
by Maxim Perevedentsev 29 Oct '15

29 Oct '15

This is a fix for commit db488c79173b240459c7754f38c3c6af9b432970 dnsmasq main process which is relied on when waiting for DAD to complete exits without actually waiting for DAD. This is dnsmasq daemon's task. It seems to be a race that DAD finished before dnsmasq main process exited. The above commit needs the execution to block until DAD finishes for bridge IPv6 address because then it closes dummy tap device. Thus we need to ensure this ourselves. So we periodically poll the kernel using netlink and check whether there are any IPv6 addresses assigned to bridge which have 'tentative' state. After DAD is finished, execution continues. I guess that is what dnsmasq was assumed to do. We use netlink to dump information about existing IPv6 addresses. Netlink's response is a multi-part message. Unfortunately, the current implementation of virNetlink treats such messages as faulty and throws an error. So the patch 2/2 adds multi-part nelink response support. Update v2: fixed syntax. Update v3: moved to virnetdev. Update v4: added DAD timeout, minor fixes.

[libvirt] [PATCH] Use correct pci addresses during device-detach

From: Nitesh_Konkar <niteshkonkar(a)in.ibm.com> The attach-device on live and persistent copies can be done independently. Thus devices can end up having different pci addresses in live and persistent copies.

[libvirt] [PATCH] rbd: Remove snapshots if the FORCED flag has been provided
by Wido den Hollander 27 Oct '15

27 Oct '15

When a RBD volume has snapshots it can not be removed. This patch introduces a new flag to force volume removal, VIR_STORAGE_VOL_DELETE_FORCED. With this flag any existing snapshots will be removed prior to removing the volume. No existing mechanism in libvirt allowed us to pass such information, so that's why a new flag was introduced.
