[libvirt] [PATCH 0/2] qemu: Update next usable PCI slot on domain reconnect
by Jiri Denemark 20 Aug '10

When libvirtd restarted and reconnected to existing domains, we didn't update nextslot so that hotplug starts with a slot next to the last used one.

[libvirt] [PATCH 00/10] start tackling *printf issues
by Eric Blake 20 Aug '10

20 Aug '10

Based on the long thread about whether %zu and %llu are safe to use, here's a series of patches to start tackling the problems. I've got more work to do, but had enough ready that it was worth posting this much for review, and can push in pieces as individual patches are ACK'd.

[libvirt] [PATCH] Add support for Vendor and Model in Storage Pool XML
by Patrick Dignan 20 Aug '10

20 Aug '10

Hi all, I wrote a patch to add support for listing the Vendor and Model of a storage pool in the storage pool XML. This would allow vendor extensions of specific devices. The patch includes a test for the new attributes as well. I'd appreciate some feedback on it, and would like get it merged when it's ready. Patch added at the bottom of the message.

[libvirt] virsh attach-disk using files and KVM
by Ryan Harper 18 Aug '10

18 Aug '10

Currently virsh attach-disk interface only accepts 'file' or 'tap' for driver type when attaching files as disks. One can succesfully attach a file as disk with: virsh attach-disk <vm> <file> <drive> --driver file --type disk which generates the following xml which is passed to libvirt: <disk type='file' device='disk'> <driver name='file' type='raw'/> <source file='/images/test02.img'/> <target dev='vdc' bus='virtio'/> <alias name='virtio-disk2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> Now, if you shutdown the guest and restart, libvirt complains that the driver type 'file' isn't supported. This is from src/qemu/qemu_conf.c:4146 where if the driver name isn't 'qemu' it rejects the configuration. How best to resolve this? Update qemu_conf.c to accept 'file' type? update virsh to allow specifying 'qemu' as a driver type for files? -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx ryanh(a)us.ibm.com

It makes sense for the FSF to request that GNU projects use better licenses. Unfortunately, libvirt is not a GNU project; so it is more a question as to how Red Hat wants to license it, rather than what the FSF prefers. At any rate, I think the ultimate decision on how libvirt is licensed is rather political in nature, and will involve quite a bit of discussion among more than just the software developers contributing to libvirt. But at least libvirt is LGPLv2+; unlike some projects (like git) that are explicitly v2-only and can't do the upgrade. Meanwhile, I tend to agree that relaxing printf-posix to LGPLv2+ is a rather hefty sledge-hammer, and probably not appropriate for gnulib. > >> since using umaxtostr penalizes 32-bit machines for converting to the >> 64-bit intermediary, maybe it's worth adding a size_t variant? > > That would be fine.

In a quick google search, I found this use of PRIdS (which is geared more for ssize_t, but the analog PRIuS would apply to size_t): http://bytes.com/topic/c/answers/506972-64-bit-portability-size_t-printf-fo… However, S is awfully short; I'd prefer something a bit longer like PRIuSIZE. Is there any other project already using gnulib that has invented a PRIuXXX name for size_t? It would also be nice if we had some prior art from glibc or even one of the BSD systems to copy a commonly-used name. Meanwhile, the idea is slightly more appealing than relicensing lots of gnulib or using the inttostr code; but it still requires auditing code and forbidding "%zu" in favor of "%"PRIuSIZE (or whatever other name we settle on). Also, it seems like we might want to create a new intttypes-plus (or inttypes-gnu) module, and leave the existing inttypes module as providing just the namespace guaranteed by glibc, while requiring the use of the new module to pollute the namespace with these new (but useful) macros. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
