Hi Michael,
Thanks for clarification. This sounds like a suitable process to get the
paravirtual drivers installed for NIC and HDD controllers.
I haven't run Zen on XenServer so can't comment beyond this. But it
looks like you are doing things properly.
? If this problem happens again ? it might be beneficial to see if
networking is up or down, ie, aside from ZenLB functions, can you
ping/ssh/etc. in/out of the ZenLB VM ?
I have run ZenLB as a KVM Based VM for a while now, and never had
problems like this.

Tim,
You can use it for the reference.
I will use the instruction below, and the Zenloadbalancer is running
as a VM in Xenserver.
I installed Xenserver Tool.
Please, review it and let me know if there is wrong way.
1.) Install Debian Lenny with "Other install media" default Template
and update it with aptitude.
Add the GPG-KEY of Citrix to aptitude:
wget -q http://updates.vmd.citrix.com/XenServer/5.5.0/GPG-KEY
<http://updates.vmd.citrix.com/XenServer/5.5.0/GPG-KEY>-O- | apt-key add -
*2.) Add XenTools ISO, mount and install it:
mount -t iso9660 /dev/cdrom/cdrom
cd /cdrom
dpkg --i Linux/xe-guest-utilities_5.6.0-xxx_i386.deb
dpkg --i Linux/debian-lenny/linux-image2.6**
*_If you have x64:_
dpkg --i Linux/xe-guest-utilities_5.6.0-xxx_amd64.deb
dpkg --i Linux/debian-lenny/linux-image2.6**
3.) Change the name of your HDD from "hda" to "xvda".
(if your HDD is "hdb", change to"xvdb", also for "hdd")
Change it in "/etc/fsta
b/" and "/boot/grub/menu.lst".
"fstab" is easy, and on "menu.lst"you have to change:
"kernel /boot/vmlinuz-2.6.x root=/dev/hda1 ro quiet"
to:
"kernel /boot/vmlinuz-2.6.x root=/dev/xvda1 ro quiet"
(or "hdb1" to "xvdb1")
*4.) Next change "tty1" to "hvc0" in: "/etc/inittab".
"1:2345:respawn:/sbin/getty 38400 tty1"
to:
"1:2345:respawn:/sbin/getty 38400 hvc0"*
5.) Now Shutdown VM.
6.) Go to any XenConsole.
Get the UUID of the VM with "xe vm-list".
*7.) xe vm-param-set uuid=<uuid> HVM-boot-policy=""
xe vm-param-set uuid=<uuid> PV-bootloader=pygrub
xe vm-param-set uuid=<uuid> PV-args="-- quiet console=hvc0"*
*8.) Now make the HDD of the VM bootable.
You need the VBD-UUID. Get it with:
"xe vm-disk-list uuid=<uuid>" .*
*9.) Activate the Blockdevice of the HDD and make it bootable:
"xe vbd-param-set uuid=<vbd-uuid> bootable=true"*
10.) After boot, use: "aptitude update; aptitude dist-upgrade" .
After every kernel update, do again Step 3.) change "hda" to"xvda" in
"/boot/grub/menu.lst"

Hi Michael,
you are certain the VM has proper driver support in place for the
paravirtual nic ? (I don't think this happens automatically.)
It may require building a stock (Debian) VM template from XenServer
into a ZenLB instance, by manually adding the apt-get repo sources and
installing it that way.. in order to be certain you have proper
paravirtual device support in place.
