[libvirt] Question about migration max downtime in domXML
by Jim Fehlig 20 Jan '15

20 Jan '15

Hi All, I've had a few user requests to add migration max downtime to the domain XML. IIRC, this was discussed on the list quite some time ago, but I'm unable to find it in the archives. My recollection is that max downtime is considered a tunable vs config and as such not included in the domXML. But domXML does contain quite a few tunables, so perhaps my memory is incorrect. Does anyone recall the details? I'd be happy to work on this if folks find it acceptable. Regards, Jim

[libvirt] [PATCH] qemu: Propagate storage errors on migration
by Michal Privoznik 20 Jan '15

20 Jan '15

There's one bug that got more visible with my patches that automatically precreate storage on migration. The problem is, if there's not enough disk space on destination, we successfully finish the migration instead of failing. Firstly, we instruct qemu to copy the storage. And as it copies the data, one write() will return -ENOSPC, eventually, to which qemu reacts by emitting BLOCK_JOB_ERROR. The event is successfully ignored by us. Then, since the block job has finished, BLOCK_JOB_COMPLETED event is emitted too. Secondly, we are not checking for the block job completion as we should. Currently, we do the check by issuing 'query-block-jobs' and then looking in the command's output for the job we are interested in. If course, we don't fail if the job is not there, in which case the number of total bytes to be transferred and bytes already transferred, well they equal both to zero. This is actually the line causing the bug as it sees both numbers equal to each other and gives green light to the actual migration. The fix consist of two parts: In the first, code handling BLOCK_JOB_ERROR is added. It's a monitor event and we should have handler for that anyway. In the second part, the code doing drive mirroring is rewritten so it waits for the events instead of querying on the monitor repeatedly.

[libvirt] [PATCH v2] network: Let domains be restricted to local DNS
by Josh Stone 20 Jan '15

20 Jan '15

This adds a new "localOnly" attribute on the domain element of the network xml. With this set to "yes", DNS requests under that domain will only be resolved by libvirt's dnsmasq, never forwarded upstream. This was how it worked before commit f69a6b987d616, and I found that functionality useful. For example, I have my host's NetworkManager dnsmasq configured to forward that domain to libvirt's dnsmasq, so I can easily resolve guest names from outside. But if libvirt's dnsmasq doesn't know a name and forwards it to the host, I'd get an endless forwarding loop. Now I can set localOnly="yes" to prevent the loop.
