Hi,

> Hello i trying start to run FreeBSD 8.2 amd64 iso image on Xen 4
I don't know about your issue.
I will add info about how my FreeBSD domU's config looks. Maybe this
will help you solving your issue. it took me long enough to have
something working.
Note on the first install I still used the tap network drivers and
accordingly something like ifconfig_rl0.
Once the kernel was installed, we can use the Xen PV drivers for disk
and network and get great performance. As you see the kernel still has
debug symbols. It was reasonably fast anyway,
dtc_admin = "xxx"
kernel = "/usr/lib/xen/boot/hvmloader"
builder = 'hvm'
memory = 256
name = "xen10"
vcpus = 1
#pae=0
#acpi=0
#apic=0
vif = [ 'mac=00:16:3E:xxx, ip=xxxx, bridge=eth0' ]
disk=[
'phy:/dev/vgxen/xen10,xvda,w',
'phy:/dev/vgxen/xen10swap,xvdb,w',
'phy:/dev/vgxen/xen10data,xvdc,w',
]
vfb = [ "type=vnc,vncdisplay=10,vncpasswd=xxxx" ]
cdrom="/var/lib/dtc-xen/ttyssh_home/xen10/"
boot="c"
nographic=0
vnc=1
stdvga=1
serial='pty'
cpus = '^0,^1,2-7' # ignore that line i think it's not even correct.
This is the kernel config:
cpu I686_CPU

cycles
options WITNESS_SKIPSPIN # Don't run witness on spinlocks for
speed
options PAE

option XEN
nodevice atpic
nodevice isa
options MCLSHIFT=12
# To make an SMP kernel, the next two lines are needed
options SMP # Symmetric MultiProcessor Kernel

# Note that 'bpf' is required for DHCP.
device bpf # Berkeley packet filter
And last, rc.conf
hostname="xxx.wartungsfenster.de"
ifconfig_xn0="inet xxxx netmask 255.255.255.224 -tso"
static_routes="dom0 default"
#route_gw="-host xxx/32 -iface -interface xn0" # Ignore that only
needed at hetzner
#route_default="default xxx"
sshd_enable=yes
inetd_enable=yes
inetd_flags=-wW
fail2ban_enable=yes
apache22_enable=yes
bacula_fd_enable="YES"
ntpd_enable="YES"
pf_enable="YES"
I hope you get it to work.
Otherwise you might want to take this to the freebsd-xen list at freebsd.org
Greetings,
Florian

the purpose of libvirt is to provide an abstraction layer hiding all
xen features added since 2006 until they were finally understood and
copied by the kvm devs.
