Re: [Xen-users] ### Problem with Xen4 on Debian as FreeBSD DomU ###

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:

And last, rc.conf

#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
