Description of problem: Installing virt-manager and friends today, and KVM, I tried to install a guest OS from within virtmanager, but it fails at the point of creating the guest machine with: Unable to complete install '<class 'libvirt.libvirtError'> virDomainCreateLinux() failed Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/create.py", line 681, in do_install dom = guest.start_install(False, meter = meter) File "/usr/lib/python2.5/site-packages/virtinst/Guest.py", line 649, in start_install return self._do_install(consolecb, meter) File "/usr/lib/python2.5/site-packages/virtinst/Guest.py", line 666, in _do_install self.domain = self.conn.createLinux(install_xml, 0) File "/usr/lib64/python2.5/site-packages/libvirt.py", line 521, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: virDomainCreateLinux() failed ' Version-Release number of selected component (if applicable): libvirt-0.3.0-1.fc7 python-virtinst-0.103.0-3.fc7 libvirt-python-0.3.0-1.fc7 virt-manager-0.4.0-2.fc7 kvm-24-1 How reproducible: Everytime Steps to Reproduce: 1.Try to create a guest machine from an iso image. 2. 3.

I think this may have something to do with the fact that I unchecked the box to allocate the whole disk storeage now - it succeeds if I leave that checked.
Oh, scrap my previous comment. If I leave the box to create the whole disk image now checked, the file is crated, but then once that completes I get the same error message as previously.
Yep, I won't expect the pre-allocation to make any functional difference - though I have noticed that sometimes the kernel is so overwhealmed with I/O from pre-allocating the disk, that the VM startup takes longer than normal & times out. I'll try and reproduce this problem. What kernel are you on, btw ?

I tried with pretty much same install parameters as your logs show and it succeeded for me. So there must be something in host environment that is different for me vs you which we need to track down & resolve. So a couple more questions - What does 'virsh --conect qemu:///system net-list --all' show when run as root ? - Did you get a /var/log/libvirt/qemu/WindowsXPProSP2.log file created, and if so is there any info in it ? - How much physical RAM have you got & how much is free - output of /proc/meminfo would be useful

Excellant - that gives me a critically useful bit of info. There is only one function called between time of opening the log file & time the first data is written to it, so this must be what is failing. Based on this I think the 'qemu' binary is missing - can you tell me if you have the 'qemu' RPM installed ? And, yes, this is needed even for KVM installs. There's a missing RPM dependancy which I think could be the cause of the trouble.
Aha, yes, I checked, and indeed qemu wasn't installed. Naively I had assumed that yum install kvm would pull in any qemu requirement - I had actually thought that kvm shipped with a modified qemu and so wouldn't need the "normal" one. Now I feel really dumb. I have installed qemu, and everything works. Very sorry for the noise and wasting your time. I'll check for a BZ for the missing dependency and make one if there isn't already one.
Have opened bug 248312 against kvm for the missing dependency. Will close this as NOTABUG.
