[libvirt] [PATCH 00/18] split virDomainDiskDef
by Eric Blake 24 Mar '14

24 Mar '14

I still have quite a bit of work to consolidate util/virStorageFile, conf/snapshot_conf.c, and the new struct in this series to all share the same common struct (basically, moving the struct created in this series over to util). But by refactoring the most common accesses to go through functions instead of direct field access, I've limited the amount of code that is actually impacted by using the new struct. In general, this series should not be changing any behavior.

[libvirt] [libvirt-python PATCH] setup: Make libvirt API XML path configurable
by Martin Kletzander 24 Mar '14

24 Mar '14

Adding a support for LIBVIRT_API_PATH evironment variable, which can control where the script should look for the 'libvirt-api.xml' file. This allows building libvirt-python against different libvirt than the one installed in the system.

[libvirt] ownership change for <readonly> disks
by Jim Fehlig 24 Mar '14

24 Mar '14

Noticed the qemu driver will change owner:group for <readonly> disks. I suspect this is intentional, but for reasons that elude me ATM. Any hints? :-) Regards, Jim

[libvirt] [PATCH] qemuDomainGetImageIds: Skip <seclabel/> without label
by Michal Privoznik 24 Mar '14

24 Mar '14

It's easy to shed the daemon these days. With this XML snippet: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/some/dummy/path/test.bin'> <seclabel model='dac' relabel='no'/> </source> <target dev='vdb' bus='virtio'/> <readonly/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> I get the SIGSEGV when starting the domain. The thing is, when starting a domain, we check for its disk presence. For some reason, when determining the disk chain, we parse the <seclabel/> (don't ask me why). However, there's no label attribute in the XML, so we end up calling virParseOwnershipIds() over NULL string: [Switching to Thread 0x7ffff10c4700 (LWP 30956)] __strchr_sse42 () at ../sysdeps/x86_64/multiarch/strchr.S:136 136 ../sysdeps/x86_64/multiarch/strchr.S: No such file or directory.
