[libvirt] pool default not starting on f10
by Jason Guiditta 06 May '09

06 May '09

Hello, hopefully this is something simple I just don't understand how to debug, but right now, it is keeping me from creating any new VMs. As stated in the subject, I am running F10, on x86_64 arch. Libvirt version is 0.6.1-5.fc10. Using virt-manager to create a new vm, when I get to the step to create a disk image, I get the error: 'Storage parameter error. internal error storage pool is not active'. Running virsh pool-start default gets me: error: Failed to start pool default error: out of memory Note there is no reason my machine would be out of memory, is has 6GB and nothing else running (and tried this right after booting) virsh pool-list --all shows default is inactive and 'yes' for autostart I would be happy to file a bug if needed, but thought I would throw this out to the list first to see if I was just unaware of some simple fix. Let me know if there are other details I can provide to make this easier to solve. Thanks, -j

[libvirt] [PATCH 0/1] NPIV node device backend
by David Allan 05 May '09

05 May '09

Here is an initial implementation of the NPIV support backend using the node device API. It only implements create. Destroy should be fairly straightforward, but I want to get the patch out to the list for comment while I continue to work. The code currently requires the device name and host number to be specified in the XML, but it does not use those values. I will clean that up. The user will not be able to specify either of those values, as they are created by the system when it discovers the newly created device. <device> <name>foo</name> <parent>pci_10df_fe00_scsi_host_0</parent> <capability type='scsi_host'> <host>99999</host> <capability type='fc_host'> <wwnn>c0001b0000000018</wwnn> <wwpn>c0001b1000000018</wwpn> </capability> </capability> </device>

[libvirt] [PATCH 0/7] Improve QEMU process startup error reporting
by Cole Robinson 05 May '09

05 May '09

Error reporting for failed QEMU processes isn't too great at the moment. A couple cases I have hit: - Trying to start a VM with a cdrom pointing to a nonexistent file. The svirt hook function choked on this and indicated as much in the domain log, but I still had to wait for the pidfile timeout (10 seconds), and the only error reported was 'Domain did not show up'. - QEMU dies quickly at startup. Happened with the pulse audio issue, or if we build cli args incorrectly. The reporting here varies: if QEMU dies before writing out the pidfile, the above case applies. If the pidfile is written, we timeout in ReadLogOutput, and it's hit or miss whether we even report the logfile output to the user. The following patches improve the above cases by ensuring we never have to wait for a timeout, and that the logfile output is always reported in the error message. Cole Robinson (7): Add documentation for __virExec and virExec virExec: Delay daemonizing as long as possible. Add helper function virExecDaemonize Report qemu log data if we fail to daemonize the process. Add pidfile argument to __virExec Check that QEMU is still alive while reading startup output.

I've imported a Windows Server 2003 as a guest using the IDE drivers. When I try to use the virtio drivers instead, Windows just blue screens. Am I stuck with the IDE drivers under Windows? -- Aaron Clausen mightymartianca(a)gmail.com
