[libvirt-users] Virsh Fail to Connect to Hypervisor
by Xu, Rongjie (Nokia - CN/Hangzhou)
Hi,
I am upgrading libvirt from 1.2.9 to 2.0.0 and I have successfully make the libvirtd running. However, virsh cannot connect to hypervisor with following errors:
virsh # connect
error: failed to connect to the hypervisor
root@node-55:/usr/local# virsh -c 'qemu:///system' connect
error: failed to connect to the hypervisor
error: no connection driver available for qemu:///system
Can you give me some suggestion about where will be the problem. Thanks.
libvirtd is running:
root@node-55:/usr/lib/python2.7/dist-packages# ps aux | grep -i libvirtd
root 1246963 0.0 0.0 1245780 3428 ? Ssl 06:04 0:00 /usr/sbin/libvirtd --config /etc/libvirt/libvirtd.conf -l
Best Regards

[libvirt-users] Default firewall rules and forwarding to a guest
by Omer Aldemir
Hello,
I am trying to understand how libvirt firewall rules are loaded as I have firewalld and iptables services are disabled.
Where is the configuration files for firewall and NAT rules for libvirt?
How can I load default firewall rules if I mess things up
Also I have realized that followings is default
ACCEPT all -- 0.0.0.0/0 192.168.122.0/24 ctstate RELATED,ESTABLISHED
but If I am to forward a port for a real IP to internal guest machine I need
ACCEPT all -- 0.0.0.0/0 192.168.122.0/24 state NEW,RELATED,ESTABLISHED
(NEW state is required) and also of course a forwarding rule
iptables -t nat -I PREROUTING -p tcp --dport 3389 -j DNAT --to-destination 192.168.122.16:3389
Is there a place I can make this rules static with LibVirt (not playing with firewalld and/or iptables service for Centos 7)
Regards.
