Hi,

I have Ubuntu 9.10 with 2.6.27.5 x86_64 kernel. The kernel was compiled
using the following guide:

Xen is 3.3. xm info is below:

virbr0          8000.000000000000       yes

When I start xend I can see the following in /var/log/syslog:
BLKTAPCTRL[17107]: blktapctrl_linux.c:23: /dev/xen/blktap0 device already
exists

When I try to start a xen vm I get the following:
Error: (1, 'Internal error', 'xc_dom_boot_domU_map: failed to mmap domU
pages 0x9fe+0x85f0 [mmap, errno=14 (Bad address)]\n')

Please help

Thanks
