[libvirt] Storage LVM volume mounted with filesystem
by Ricardo Tiago 02 Sep '08

02 Sep '08

Hi, I'm quite new to libvirt, and i have a question regarding the storage capabilities in libvirt. I have reading the documentation but i couldn't figure it out if its possible to specify in the LVM volume xml description that i want the new volume to be mounted with a filesystem. I'm using libvirt-0.4.4 My current volume xml is: <volume type="fs"> <name>sl5-root</name> <allocation>0</allocation> <capacity>5000000000</capacity> <target> <path>/tmp/sl5</path> <permissions> <owner>0744</owner> <group>0744</group> <mode>0744</mode> <label>virt_image_t</label> </permissions> </target> </volume> /tmp/sl5 is a ext3 filesystem that i would like to see mounted in the newly create lvm volume. My pool xml: <pool type="logical"> <name>vg1</name> <target> <path>/dev/vg1</path> </target> </pool> Thanks Ricardo

[libvirt] [PATCH] Set correct device type when parsing input devices
by Cole Robinson 02 Sep '08

02 Sep '08

In virDomainDeviceDefParse, parsing an input device was actually setting it's type as DEVICE_DISK. The attached patch fixes this.

[libvirt] [PATCH] Don't list capabilities entries if emulators can't be accessed
by Cole Robinson 02 Sep '08

02 Sep '08

The patch below fixes capabilities xml generation for the qemu driver if the emulators aren't found in the hardcoded paths. Current behavior will add a <guest> entry for the emulator even if it does not exist, patch fixes this to check that we actually have access. This brings up another issue, that hardcoded paths aren't exactly distro friendly. I'm not really familiar with what options we have to allow specifying these at build time (or something else). Anyone have an idea?

[libvirt] Reminder about developer IRC channel
by Daniel P. Berrange 02 Sep '08

02 Sep '08

There're a few new people contributing patches to libvirt recently, so just thought I'd remind people that many of us hang out on IRC. The channel is #virt on irc.oftc.net. If we seem to be ignoring patches[1] you've sent, then do send nag-emails to this list, or say hello on IRC to ask about the status of things (most of us are currently on a European timezone) Regards, Daniel [1] We're not delibrately ignoring them - things just get missed / forgotten / delayed sometimes due to other things we work on. -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

[libvirt] PATCH: 0/5: Enhancing the virExec function
by Daniel P. Berrange 02 Sep '08

02 Sep '08

The following series of patches do a bunch of work on the virExec function. Overall this leads to a more robust implementation with better error reporting, and an increased level functionality. This lets us remove all uses of fork/exec in libvirt and replace them with virExec. This was all motivated by some fork/exec bugs discovered when refactoring LXC driver which have potential to affect every use of fork/exec in our code.

[libvirt] remote driver?
by Jun Koi 01 Sep '08

01 Sep '08

Hi, I am connecting to libvirtd with virsh using qemu:///system connection type. However, it seems virsh uses "remote" driver for all the action on the VM. So this means qemu:///system considers all the action is done "remotely" even if it is on the same physical machine? I really expected that it uses "QEMU" driver, but that is not the case. So I wonder in which case "QEMU" driver is used? Many thanks, Jun
