>How-To-Repeat:
1. Get Xen Dom0 installed.
Xen version: 3.0.3 x86_64
The same isuue reproduced on Xen 3.4.2 x86_64 too.
2. Get FreeBSD DomU image ready like described at:
http://forums.freebsd.org/showthread.php?t=10268
3. FreeBSD DomU config file:
# cat /etc/xen/nynU5Rfkh02U
kernel = "/var/lib/xen/images/kernel.nynU5Rfkh02U"
memory = "110"
name = "nynU5Rfkh02U"
vcpus = "1"
vid = "13"
sanip = "10.200.200.19"
vif = [ 'mac=00:16:3e:f3:a5:6f, bridge=xenbr0, ip=68.169.47.45, vifname=nynU5Rfkh02U, rate=0Mb/s' ]
disk = [ 'phy:/dev/iscsi_0_13,sda,w', 'phy:/dev/iscsi_0_133,sdb,w' ]
extra = "boot_verbose=1"
extra += ",vfs.root.mountfrom=ufs:/dev/da0"
extra += ",kern.hz=100"
4. Create Xen DomU, run:
# xm create nynU5Rfkh02U -c
