I am using Fedora Core 6. My VM freezes and on the console I see the message blk_tap: Can''t get UE info! My system has 4 Gigs of ram. My VM is a file backed vm using a non sparse file. I used the following virt install to install it. virt-install --nonsparse -l http://192.168.1.114/fc6/ -f /var/lib/xen/images/ossim.img -s 5 --nographics -n ossim -r 512 Any ideas what is causing this blocking? brian -- Brian Lavender http://www.brie.com/brian/
