Not only the initialisation is slow, also further I/O stalls the dom0. This is an Intel 945GM/E chipset, with an IDE-CF-Card as / (ext3) filesystem and an IDE-2.5" hardisk (/home, ext4). IDE-CF-card is slower, only able to read/write about 35MBytes/second, the 2.5" HDD is at about 55MBytes/sec. Both, the ISO-image and the virtual harddisk are on the /home directory and therefore on the harddisk. Is there maybe an I/O problem? Dom0 is able to do everysth. like usual on all filesystems, both disks are without errors.
