RE: [Xen-users] PV 0.9.12-pre3 with Multiple NICs/Bridges,Hard Lock - Update - ODBC connector not compatible?
What version of XEN are you running?
Also, I don't normally see the hpet and hap options specified in domU
configs - what's your reason for changing these from the defaults?

Hi Nick,
The event viewer on the VM shows nothing much at all. There are a couple
of XenVBD errors about internal data structures but these do not happen
on most boots.
Xm dmesg logs nothing, xm log shows debug information on creation of the
VM but nothing after that.
Here is the VM config using only the LAN bridge:
name = 'dns2'
maxmem = 768
memory = 768
vcpus = 1
cpus = ["7"]
builder = 'hvm'
kernel = '/usr/lib/xen/boot/hvmloader'
pae = 1
acpi = 1
apic = 1
hpet = 0
hap = 1
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
device_model = '/usr/lib64/xen/bin/qemu-dm.drbd'
sdl = 0
vnc = 1
vncdisplay = 9
vncpasswd = ‘pass'
disk [
'phy:/dev/drbd9,hda,w','file:/mnt/xenmedia/w2k3.iso,hdc:cdrom,r'
]
boot = 'd'
vif = [ 'mac=00:16:3e:44:d3:aa,bridge=lanbr' ]
serial = 'pty'
Any ideas on what might be causing this?
Thanks,
Rob

Could you post your Xen domU configuration? Also, are there any Events
in the Event Log upon reboot that indicate why it hard locks? Any
output in "xm dmesg" or "xm log" that may be related?

I have done some more testing and the problem is not related to having
two NICs, I think it is something to do with traffic going across the
LAN. Using WAN or LAN bridge is OK, using WAN or LAN MAC is OK but as
soon as Lan IP comes up I get a couple of pings before the VM hard
locks.
The only service running on the LAN is an SQL Server 2005 Native Client
ODBC connection to another system on the same LAN network. How do I go
about debugging/fixing this?
Thanks,
Rob

Lock
Hi Everyone,
I'm using a Xen 3.30 on Centos Dom0 setup with two bridges, one for WAN
and One for LAN (Both are on separate physical NICs within Dom0).
I can use a 2 NIC setup with Server 2003 Pure HVM fine. A single NIC
setup works fine with the Pre3 drivers but as soon as I add the second
NIC the system hard locks within a few seconds of networking coming up.
Both NICs looks fine from device manager and Network connections.
Any ideas how I can get this working with 2 NICs. Is a different version
of the GPL PV driver more likely to work?
Thanks in advance,
Rob
