[libvirt] qemu and <transient/> disks
by Richard W.M. Jones 24 Jul '12

Partly following up this message: https://www.redhat.com/archives/libvirt-users/2011-October/msg00142.html > > And what about qemu's option "snapshot=on" ? > > Unreliable. It won't work with SELinux (since qemu tries to create the > snapshot on /tmp), and it makes your guest unmigratable. I think that > it is easier to have libvirt use qemu-img to create a qcow2 wrapper > prior to booting the guest, at which point the solution is easier to > control from an sVirt perspective, and is more likely to allow us to > figure out a way to make things work with migration (at least, I'm > hoping I can figure out how to migrate a guest with a transient disk). Lack of this feature is pretty annoying, particularly since (a) libguestfs needs it and (b) it's a trivial patch to add snapshot=on to the qemu driver. So to concentrate on the two objections above: - Why is SELinux concerned about qemu creating and using a file in /tmp? Obviously it should stop qemu opening and reading random files from /tmp but that would be a different rule surely? - The documentation actually states that using <transient/> may make your guest unable to migrate, and in any case we don't care. > But if you want to use qemu's snapshot=on in the meantime, you can > use the <qemu:commandline> namespace XML to add it. Is there an example how to do this? It seems like it might be possible using a global qemu '-set device.<id>.snapshot=on' parameter, but how can I know what <id> libvirt will give to a '-drive' parameter? (I found from experimentation that it's something like "drive-virtio-disk0", but I can't track down the bit of code that produces this string yet ...)

[libvirt] [PATCH] Make ESX & Hyper-V code generator safe with parallel builds
by Daniel P. Berrange 23 Jul '12

23 Jul '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> If from a clean GIT checkout 'make -j 8' is run, the ESX and Hyper-V code will be generated multiple times over.

[libvirt] [PATCH libguestfs 0/4] Add a libvirt backend to libguestfs.
by Richard W.M. Jones 23 Jul '12

23 Jul '12

This preliminary patch series adds a libvirt backend to libguestfs. It's for review only because although it launches the guest OK, there are some missing features that need to be implemented. The meat of the patch is in part 4/4. To save you the trouble of interpreting libxml2 fragments, an example of the generated XML and the corresponding qemu command line are attached below. Note the hack required to work around lack of support for '-drive [...]snapshot=on' Some questions: - I've tried to use the minimum set of XML possible to create the guest, leaving libvirt to fill out as much as possible. How does this XML look? - The <name> is mandatory, and I generate one randomly. Is this a good idea? I notice that my $HOME/.libvirt directory fills up with random files. Really I'd like libvirt to generate a random name and just deal with the logfiles. - How do we query libvirt to find out if qemu supports virtio-scsi? - Will <source file> work if the source is a host device? - Since when has <memory unit> attribute been available? For example, is it available in RHEL 6? - I'm using type="kvm" and I've only tested this on baremetal, but I don't want to force KVM. If only software emulation is available, I'd like to use it. - Is there an easy way to get -cpu host? Although I have the libvirt capabilities, I'd prefer not to have to parse it if I can avoid that, since libxml2 from C is so arcane. Comments: - <source mode> attribute is undocumented.

[libvirt] [PATCHv2 0/6] Add usb controller model="none"
by Peter Krempa 23 Jul '12

23 Jul '12

This is a rebase of the previous version. There are no changes except solving conflicts in tests/qemuxml2argvtest.c after new tests were added lately. This series adds support for completely disabling USB bus for a host if a user requires this. For this to work a new USB controller model "none" was added that removes the USB bus. The controller is added in patches 2-4. Patch 1 cleans up some nits (and is not necessary) and patches 5 and 6 tweak qemuxml2argvtest and add tests to check the new controller. Peter Krempa (6): maint: Clean up coding style domain_conf: Add USB controler model "none" domain_conf: Add helpers to verify if device configuration is valid qemu: Add support for "none" USB controller tests: Add support for catching domain XML parsing errors tests: Add tests to check the new USB "none" controller docs/schemas/domaincommon.rng | 1 + src/conf/domain_conf.c | 121 +++++- src/conf/domain_conf.h | 6 + src/libvirt_private.syms | 2 + src/qemu/qemu_command.c | 29 +- src/qemu/qemu_driver.c | 13 +- .../qemuxml2argvdata/qemuxml2argv-usb-none-hub.xml | 19 + .../qemuxml2argv-usb-none-other.xml | 19 + .../qemuxml2argv-usb-none-usbtablet.xml | 21 + tests/qemuxml2argvdata/qemuxml2argv-usb-none.args | 5 + tests/qemuxml2argvdata/qemuxml2argv-usb-none.xml | 16 + tests/qemuxml2argvtest.c | 515 ++++++++++---------- 12 files changed, 495 insertions(+), 272 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none-hub.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none-other.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none-usbtablet.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none.xml -- 1.7.8.6
