The kernel reports a device in use and udev kills workers (see attachment). After this it is not possible to start a pv guest and a dom0 reboot is necessary. Probably it is a timing problem. Inserting "time.sleep(1)" below the line blcfg = bootloader(blexec, fn, ... in file /usr/lib64/python2.7/site-packages/xen/xend/XendDomainInfo.py solves the problem.
