[libvirt] [PATCH 0/2] Give each virtual network bridge its own fixed MAC address
by Laine Stump 14 Feb '11

14 Feb '11

This fixes https://bugzilla.redhat.com/show_bug.cgi?id=609463 As usual for me, this series has a problem searching for a more elegant solution. See PATCH 2/2 for details. Is it too late to put this in 0.8.8? (assuming a solution to that problem, of course).

[libvirt] Entering freeze for libvirt-0.8.8
by Daniel Veillard 13 Feb '11

13 Feb '11

We're entering the week freeze for 0.8.8, so let's delay new feature until the end of next week and let's focuse on bug fixes. I have put an initial release candidate at: ftp://libvirt.org/libvirt/libvirt-0.8.8-rc1.tar.gz it seems to compile and work fine for me. there is however a small problem at configure time: ------------------------------------- thinkpad:~/tmp/libvirt-0.8.8 -> ./autogen.sh --system ; make Running ./configure with --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib fatal: Not a git repository (or any of the parent directories): .git fatal: Cannot open 'bootstrap.conf': No such file or directory usage: git diff [--no-index] <path> <path> /home/veillard/tmp/libvirt-0.8.8/tmpwrk2661/archive /home/veillard/tmp/libvirt-0.8.8/tmpwrk2661/archive /home/veillard/tmp/libvirt-0.8.8/tmpwrk2661/archive Copying file m4/codeset.m4 ------------------------------------- Seems some git command is launched but errors out, that's normal but it should not pollute the output (there is also the extra paths output but that's due to the fact that I use CDPATH env variable and as a result "cd dir" is not silent when successful but output the target dir).

[libvirt] Unix socket credentials on OSX?
by Justin Clift 12 Feb '11

12 Feb '11

Hi all, Interestingly, MacOS X has a working PolicyKit port, providing version 0.96. Attempting to build libvirt 0.8.7 against it gives this error though: libvirtd.c:1298:4: error: #error "UNIX socket credentials not supported/implemented on this platform yet..." Does anyone have an idea of whether implementing Unix socket credentials for OSX would be a big task, or a small one, or ? I'm thinking this could be what's needed to let qemu+ssh:// connections from OSX to RHEL/Fedora servers work. Not critical at all, but would be nice, etc. :) Regards and best wishes, Justin Clift

[libvirt] [PATCH v2] xen: Prevent updating device when attaching a device
by Osier Yang 12 Feb '11

12 Feb '11

When attaching a device that already exists, xend driver updates the device with "device_configure", it causes problems (e.g. for disk device, 'device_configure' only can be used to update device like CDROM), on the other hand, we provide additional API (virDomainUpdateDevice) to update device, this fix is to raise up errors instead of updating the existed device which is not CDROM device.
