Hello,I installed Xen 3.2.1 on Debian Lenny from packages. Then created image files with 'xen-create-image --size=2Gb --swap=128Mb --dhcp --dir=/xen --hostname=test'. Now I'm trying to run Debian in PV mode using the following configuration file: kernel = "/boot/vmlinuz-2.6.26-1-xen-686" ramdisk = "/boot/initrd.img-2.6.26-1-xen-686" memory = 128 name = "test" vif = [ '' ] dhcp = "dhcp"disk = ['tap:aio:/xen/domains/test/disk.img,xvda1,w', 'tap:aio:/xen/domains/test/swap.img,xvda2,w'] root = "/dev/xvda1 ro" extras = 'console=xvc0' And get the running process to hang on disk initalization stage: Started domain test [ 0.004000] .init : 0xc038d000 - 0xc03be000 ( 196 kB) [ 0.004000] .data : 0xc02ccd00 - 0xc03858a0 ( 738 kB) [ 0.004000] .text : 0xc0100000 - 0xc02ccd00 (1843 kB)[ 0.004000] Checking if this processor honours the WP bit even in supervisor mode...Ok.

Also I created a few HVM domUs with FreeBSD and Windows and everything was fine with tap:aio driver. xend.log does not contain any error messages. When I change tap:aio to file: PV domU is loaded fine. But I want to loadWhere is the problem? I guess something is wrong with blktap driver in domU kernel (that is the same as dom0)? Also I've noticed in syslog.log error messages about blktapctrl: Dec 26 12:45:49 vps-main BLKTAPCTRL[24550]: Found driver: [raw image (aio)] Dec 26 12:45:49 vps-main BLKTAPCTRL[24550]: Found driver: [raw image (sync)]Dec 26 12:45:49 vps-main BLKTAPCTRL[24550]: Found driver: [vmware image (vmdk)] Dec 26 12:45:49 vps-main BLKTAPCTRL[24550]: Found driver: [ramdisk image (ram)] Dec 26 12:45:49 vps-main BLKTAPCTRL[24550]: Found driver: [qcow disk (qcow)]Dec 26 12:45:49 vps-main BLKTAPCTRL[24550]: couldn't find device number for 'blktap0' Dec 26 12:45:49 vps-main BLKTAPCTRL[24550]: Unable to start blktapctrlI sucesfully load xenblktap manually with modprobe, restart xend but with any luck about tap:aio hanging in domU. Can anyone help please to solve this issue?
