Save and restore DomU (hvm) on Dom0 restart. CentOS 5.5 + Xen 3.4.3
What are the settings that I must specify to have DomU be saved and then
automatically started on reboot of the physical server?
In my /etc/sysconfi/xendomains it points to a save folder (which does not exist)
My configuration files are located at /vm/cfg/vm-xxxx/vm-xxxx.xen
In my config file I have:

Secure Xen neworking help (route, ebtables, private network)
I need some help to configure a secure network on my Xen server. I have been
looking online and it seems a I need a routed network. But I am having a
terrible time implementing it.
My setup:

All guests will be HVM
What I want to do is something similar to a firewall and port forwarding.

Missing packets on Dom0 when sniffing bridge with wireshark/tethreal
Hi,
I have a Centos5 machine running xen 3.0.3-41 with two NICs each on its own
subnet: 192.168.1.x and 192.168.0.x. All DomUs can talk to each other OK
through two xen bridges. There are 3 DomUs: Dom0, Dom1 and Dom2
The scenario:
I''m trying to capture packets on Dom2 on 192.168.0.x from external devices
that are sending SIP stuff to Dom1, but fail to capture any packets. I

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

[SPAM] Xen bridge network issue
Hi,
I have taken the long and winding road and indeed it lead me to your door. I
need your help, please.
My Xen includes 2 guests. Xen itself (10.2.0.52) gets free access to the
outside world and to its guests.
Both guests however (10.2.0.54/10.2.0.55) see each other but stay under
house arrest!
Not a single ping manages to go past the bridge (xenbr0) and get an answer
from the default gateway

Bug#571634: bridge loosing connection
Hi,
I'm not sure but I think I suffer under the same problem with a bit
different setup with squeeze testing and xen 4.0rc5.
In fact I'm using bridges in the dom0 and the connections to the domU
get lost sporadically.
In don't see where's a solution to the problem... Is it now a bug? When
it's an iptables bug, where's the corresponding bug in the iptables

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'']

Dom0 cannot see network when bridge is enabled
I''ve seen a lot of threads w/ similar problems, but none have posted a
resolution.
I am using Debian 4.0r1 (Etch). I was using the xen packages from
stable, but have tried w/ testing as well and the problem persists.
http://pastie.caboo.se/95144
Host is 10.0.0.20 on network 10.0.0.0/24.
Dom0 is thus 10.0.0.20
DomU is 10.0.0.30
When the bridge is enabled, DomU can ping everything.

Xen Networking problem!
Hi,
I ''ve got a CentOS 5.2 server running xen 3.0 with 2 DomUs also running
CentOS 5.2.
All my boxes are up-to date.
I''m experiencing trouble with networking.
Dom0 can reach the outside world when no DomU are started. It can also
reach the outside world when only one DomU is running.
The troubles begin when I start the second DomU. At first, this new

XEN/bridge mode
Hi!
I want to forward the port 3389 from the domU to the virtual server with ip
address 192.168.122.77 with not success...
I tried a lot of iptables rules with no luck so far. Is this possible? I
take a look at other post and I don''t found an answer.
By example:

Compiling from source and networking problem
Hey,
I was originally asking questions on xen-users but no one seems to have any
idea about this so I figured I''d try this list.
I compiled Xen from source (3.2 testing) on an Intel machine running Fedora
Core 8 and have discovered that my guest (Windows Vista) does not have a
network connection.
Looking at various online documentation and a machine that does work, I
guessed that I

Debian Squeeze hangs with kernel 2.6.32-5-xen-686
Hi all!
After upgrading to Squeeze, I am watching a Xen VMHost that after a
while it hangs. This did not happen when I was using Xen with Debian
Lenny (in this case as with Squeeze, the Xen components are from Debian
repositories).
In each case I connected a keyboard and monitor to the computer and the
screen remained black without answering any key.
This problem seems to also affect domUs,
