[libvirt] libvirt git doesn't know to use -no-kvm on qemu-kvm 1.2
by Cole Robinson 17 Dec '12

17 Dec '12

Libvirt git isn't correctly starting plain qemu guests when using qemu-kvm 1.2 (on Fedora 18). The problem is that -no-kvm is not passed to the binary, so the default mode is used, which is kvm=enabled. The issue comes from capabilities probing: we probe against 'qemu-kvm -M none', which responds to 'query-kvm' with enabled=False, when regular invocation is enabled=True. We should be able to work around this by using -machine ...,accel=kvm|tcg unconditionally for qemu >= 1.2, and not have to do the -enable-kvm/-no-kvm dance. accel= has been around for a while and libguestfs uses it so it should be reliable. - Cole

[libvirt] [PATCH v3 0/4]use newer video device by -device in qemu commandline
by Guannan Ren 17 Dec '12

17 Dec '12

v2: Check qemu version, it has to be qemu >= 1.2 for using new video device with -device qemu option v3: Add a new caps bit QEMU_CAPS_1DOT20_PLUS to mark qemu >= 1.2 Add a new testcase for improved qemu commandline Fixed all placed pointed out in v2 This patch set aims to use qemu VGA device with -device option to replace -vga option. The mapping is as follows. '-device VGA' maps to '-vga std' '-device cirrus-vga' maps to '-vga cirrus' '-device qxl-vga' maps to '-vga qxl' (there is also '-device qxl' for secondary devices) '-device vmware-svga' maps to '-vga vmware' Through this change, guests will be able to use any available PCI slot number rather than fixed 0x2 slot for primary video device.

[libvirt] [PATCH] Support custom 'svirt_tcg_t' context for TCG based guests
by Daniel P. Berrange 17 Dec '12

17 Dec '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> The current SELinux policy only works for KVM guests, since TCG requires the 'execmem' privilege. There is a 'virt_use_execmem' boolean to turn this on globally, but that is unpleasant for users. This changes libvirt to automatically use a new 'svirt_tcg_t' context for TCG based guests. This obsoletes the previous boolean tunable and makes things 'just work(tm)' Since we can't assume we run with new enough policy, I also make us log a warning message (once only) if we find the policy lacks support. In this case we fallback to the normal label and expect users to set the boolean tunable Signed-off-by: Daniel P.

[libvirt] Some help in Starting up
by Arslan Waqar 16 Dec '12

16 Dec '12

Hi everyone! I hope you bear with me, and I would be grateful for that, as I am very new to all this... I want to develop for libvirt and want to specifically work on it for the VirtualBox domain. The problem is I have no idea how to set up my development environment... I have a ubuntu 64 bit machine with me, with The latest Virtual box installed (from the official site), and git already installed. Now what am I suposed to do? get libvirt code from the git repository? if that is so then what would be the next step? -- Regards, Arslan Waqar.
