HVM Network Interfaces
Hi Everyone,
In my HVM guest''s config file, I have given my guest 3 interface. I have
called them fw1, fw2 and fw3. I have joined each interface to a bridge
on the Dom0. This does appear when I do a "brctl show". However, there
are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where
x is the domain ID for the guest). Furthermore, I am only able to run

No connection in DomUs with network-route
Hi,
I would like to know if somebody can point me out how to configure
several DomUs in a private LAN (for example 192.168.100.0/24) and one
DomU with two interfaces (one - 192.168.100.0/24 and two - internet).
So far I have enabled in xend-config.sxp:
(network-script network-route)
(vif-script vif-route)
My config files have:
/mnt/VM/1.cfg:vif = [''ip=192.168.1.3'']

pfSense HVM
Hi Everyone,
Does anybody have any experience using pfSense on Xen? I would most
probably have to use HVM...
My idea would be to use PCI-Passthrough to the pfsense DomU, and only
make the Dom0 accessable via the pfsense firewall
Thanks
Jonathan

Ubuntu 10.04 DomU Xen 4.0
Hi Everyone,
How does one install Ubuntu 10.04 DomU in PV mode when running Xen 4.0? My Dom0 is also running 10.04.
Can I still use the CD?
Thanks

Recent hypervisor update on Debian Wheezy breaks domU networking
Hi,
Firstly I apologise for the cross-post, however I don't expect to get as
quick a response from the package maintainers as I do from the Debian
community, and this issue affects a service that I've got scheduled to go
live at midnight this evening. :(
A recent update from xen-hypervisor-4.1-amd64 version 4.1.3-7, to version
4.1.3-8 on Debian Wheezy has caused all vm's on this host

Convert HVM to PV
Hi Everyone,
To convert an HVM install to PV, is it just as simple as creating a new config file, and use the "kernel" and "initrd" parameters to boot from a XEN kernel stored in the Dom0, and use the (ex) HVM''s disk image in the "disk" parameter?
Or is there something else I am missing?
Thanks

VT-x not found..
Hi Everyone,
I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide:
http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/
Now, using the new kernel that it gave me, the system doesn''t seem to be
able to detect vt-x..
In virt-manager, Local Install Media and Network Boot are greyed out..
Any ideas?
Thanks

Network problem: packets are lost in domU
Hello,
I am having big problems with Xen virtual network interfaces. First
I tried typical bridge support, no luck. The packets sent from dom0
to domU seemed to disappear somewhere. Then, to debug the problem
I have set up a simple point-to-point link and still have the same
problem.
I am using Xen 3.0.4-1 and Linux 2.6.16.x in both dom0 and domU.
I have tried kernel 2.6.16.35 and 2.6.16.41.

Unable to get Networking on HVM Domain

I grabbed xen-3.3.1 sources from the Mercurial repository
(xen-3.3-testing.hg, changeset 475:1cf755387728, from Oct. 23, 2008) and
built Xen from these sources on a 32-core (8 quad core Barcelona CPUs)
SunFire machine, running an Ubuntu 8.04 (Hardyy Heron) distribution.
Everything seemed to be going OK until I booted an HVM (also Ubuntu 8.04)
domain. That domain boots normally but

Install ubunto domU
Dear *,
I''m more used to work with RedHat like OSes. Still, I did not denied the
request from a user who wants a domU based on ubunto. I usually use
virt-install to do the job, with a script similar to this one:
#!/bin/sh
BASE=SL-4.7-i386-pv \
virt-install --nographics \

Promiscuous mode
Hi Everyone,
In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created?
# Accept packets leaving the bridge going to the domU only if
# the destination IP for that packet matches an authorized IPv4
# address for that domU.
iptables -A FORWARD -m physdev --physdev-out vif1.0 \
--destination 216.146.46.43 -j ACCEPT

bridge + arp
Hi,
this is propably bridge related and not really a xen problem, but it
might help someone:
Some of our domUs are not able to arp. Arp -n show (incomplete), and
doing a tcpdump shows, that on the dom0''s eth0 the arp request goes out,
the response comes in, but on the vifX.0 interface the arp response is
gone.

DOMU loses outside connection
When I start xen dom0 I get that same dhcp address for eth0 and for
xen-br0, dom0 can talk to the world. If I start each of my 3 domU''s
mannually, each guest gets a xen-br0 vif with a dhcp address and all 3
can talk to the outside world and each other (my "flat network").
What I want is a tiered network with the first domU acting as a firewall

Query - Issue creating VMs when not using bridge that Xen created, but using ovswitch.
*Hello,*
I have installed Xen as Hypervisor with OpenSUSE running in Dom0. I want to
use ovswitch (ovs) instead of the bridges that Xen created. In order to do
so, I installed ovs in dom0 just like for the plain Linux.
Xen has replaced eth0 with peth0, and has created a bridge named eth0. And
eth0 is connected peth0 interface , vif2.0 interface (VM), and everything
is working fine. Now I delete

outgoing domu network dies after a while
I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine
for a few months.
This past weekend it suddenly started to act up and after some
troubleshooting I can now say that it seems like the guests(domU) loose
the outgoing network pipe, from the console I can see that the TX
counter is stuck at the same value but it''s no errors. It behaves as if
