[libvirt] [PATCH 0/3] Fix a couple of virtual network dnsmasq bugs
by Laine Stump 12 Mar '11

12 Mar '11

(sorry for the previous message sent from "root" - I mistakenly ran git send-email from a shell that was su'ed, and realized my mistake midstream) The first of these bugs is a regression that I didn't notice until it was reported on libvirt-users list a couple days ago. The second is a long-standing problem that I'm sure I saw discussed either on one of the libvirt lists, or in a RHEL, Fedora, or upstream libvirt bugzilla report, but can't find it right now.

[libvirt] login and password in connection string for vmware hypervisors...
by john alexander sanabria ordonez 11 Mar '11

11 Mar '11

Hi, I want submit commands against a VMWare hypervisor via virsh in a non-interactive way. I can connect to my [remote] hypervisor via virsh as follows: virsh -c gsx://ic-p19-01?no_verify=1 then, it asks me for login and [root] password and I'm in. What mechanism can be used to submit commands, e.g. virsh -c gsx://localhost?no_verify list --all, with no password at all? A modified version of the connection string is required? what is the structure of that connection string? Additional parameters to the 'virsh' command? Thank you,

[libvirt] [PATCH] RFC: support "vram" and "heads" for qxl vga
by Osier Yang 11 Mar '11

11 Mar '11

qemu command line to specify "vram": -global qxl.vram_size=uint qemu command line to specify "heads", (no need of '-device' for the first 'head'): -device qxl,id=qxl-N (N is natural number) This patch is just about the command line building, still left work on the command line parsing (hacking on "qemuBuildCommandLine"), as I'm even not sure if it's the right way to build the command line.

[libvirt] [PATCH 2/2] Ignore backing file errors in FS storage pool (v3)
by Philipp Hahn 11 Mar '11

11 Mar '11

Currently a single storage volume with a broken backing file will disable the whole storage pool. This can happen when the backing file is on some unavailable network storage or if the backing volume is deleted, while the storage volumes using it are not. Since the storage pool then can not be re-activated, re-creating the missing or deleting the now useless volumes using libvirt only is impossible. To "fix" this case, all errors detected during storage pool activation are now (silently) ignored. Errors are still logged by the called functions, which have more knowledge on the detailed error condition. To reproduce: dir=$(mktemp -d) virsh pool-create-as tmp dir '' '' '' '' "$dir" virsh vol-create-as --format qcow2 tmp back 1G virsh vol-create-as --format qcow2 --backing-vol-format qcow2 --backing-vol back tmp cow 1G virsh vol-delete --pool tmp back virsh pool-refresh tmp After the last step, the pool will be gone (because it was not persistent). As long as the now broken image stays in the directory, you will not be able to re-create or re-start the pool.

[libvirt] Question about PHP licencing for libvirt-php (php-libvirt for Fedora)
by Michal Novotny 11 Mar '11

11 Mar '11

Hi, I don't know who's the right person to ask so I'm posting this into the libvir-list. We're going to have the libvirt-php package in Fedora (but renamed to php-libvirt only) but I don't know about the licencing. The licence in the SPEC file (by Lyre) is set to "PHP" however the licence file describes the GPL licence. My question is whether somebody does know whether it's OK to write a PHP extension under GPL licence or whether we need the PHP licence for this. Anybody knows? Thanks a lot for your reply, Michal -- Michal Novotny<minovotn(a)redhat.com>, RHCE Virtualization Team (xen userspace), Red Hat

[libvirt] [PATCH 0/6] new virsh command "blkiotune" support
by Gui Jianfeng 11 Mar '11

11 Mar '11

Hi All, This series implements a new command "blkiotune" for virsh. A lot of code borrows from memtune. You are able to tune blkio cgroup tunables by this command as follows. Show tunables #virsh blkiotune My_guest weight : 900 Tune tunables(Set IO weight) #virsh blkiotune My_guest --weight 500 #virsh blkiotune My_guest weight : 500 Thanks, Gui
