Description of problem: I'm trying to install a ubuntu 11.04 virtual machine, just to see if I can use spice and qxl and such duing the install, and before I get that far, I get the error: Unable to complete install: 'internal error no disk format for /zooty/salvage/iso-images/ubuntu/11.04/amd64/ubuntu-11.04-alternate-amd64.iso and probing is disabled' If disk format probing is gonna be disabled by default, shouldn't virt-manager provide an initial definition that has the right format info for an iso image file? (And what would that format be, by the way - I certainly have no idea :-). Version-Release number of selected component (if applicable): virt-manager-0.8.7-4.fc15.noarch How reproducible: every time Steps to Reproduce: 1.use virt-manager to try and install a new machine 2.point it at an iso image file as source for install 3.get the above error Actual results: disk format error Expected results: install starting from iso image Additional info:
OK, despite the error it was printing, this apparently has nothing to do with disk probing. I forgot that I had edited qemu.conf to explicitly enable disk probing by uncommenting the line for that option near the bottom, and I also had uncommented the user and group = root lines. When I put back the original qemu.conf file, and rebooted to make sure everything was reinitialized properly, then it seems to be able to boot from the iso image. I have no idea why that was the error I was getting.
Hmm, not sure either. If you can still reproduce, can you provide virsh dumpxml $vmname /var/log/libvirt/qemu/$vmname.log Closing as NOTABUG for now
