I've updated the kernel to 2.6.18-238.1.1.el5xen and left Xen at xen-3.0.3-94.el5_4.1. Didn't help, so I just updated to the latest 5x repository, updated all packages on the physical system and rebooted. That didn't help, either, and the symptoms are still the same, ie. with "serial='pty'" it gets stuck when detecting serial ports, and with that commented out, it freezes after "ide1: BM-DMA...". I've tried all permutations of "tap:aio" and "file:" for backend and "hda" and "ioemu:hda" for the frontend in the following disk configuration: disk = [ 'file:/root/image-pseudo-callisto,hda,w' ] I should probably mention that I can import the underlying image to virt-manager running on a completely independent machine with Gentoo Linux just fine, and it starts without any problem in there. Suggestions are much appreciated. With kind regards, Jan
