FYI: a short guide to libvirt & network filtering iptables/ebtables use
I just wrote this to assist some Red Hat folks understanding
what libvirt does with iptables, and thought it is useful info
for the whole libvirt community. When I have time I'll adjust
this content so that it can fit into the website in relevant
pages/places.

Is libvirt supported on Citrix Xenserver?
Hi,
I was finally able to connect to the xenapi hypervisor using virsh of libvirt 0.9.2. However, once I connect to virsh and give a 'quit' command I get "* glibc detected *** virsh: double free or corruption (fasttop):". Please find below the actual memory dump.
Note: I have disabled the SSL certificate verification in

Libvirt and iptables rule order
Hi,
On RHEL 5.5, I set up iptables rules for forwarding ports to some of my
virtual machines. For example.
iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 3380 -j DNAT
--to-destination 192.168.123.2:3389
iptables -I FORWARD -d 192.168.123.2 -i eth0 -p tcp -m tcp --dport 3389
-m state --state NEW -j ACCEPT
These worked fine, and I saved them with 'service iptables save'.

Can you check with `doveconf -nc /path/to/director.conf` that the values are actually set correctly?

Do you have !include or !try_include in director.conf? The conf.d files are not included otherwise.
