Hello, I don't know if I am writing to the proper place, but I've been struggling quite a long time with connecting to libvirtd. Any information would help. My goal is to start remote tcp connection (afterwards - tls, but later) and connect to the libvirtd. http://libvirt.org/uri.html#URI_remote There are some nitoces when starting libvirtd: -~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~- xen:/usr/local/etc# libvirtd 17:53:42.153: error : virRun:847 : internal error '/sbin/iptables --table filter --insert FORWARD --destination 192.168.122.0/255.255.255.0 --out-interface virbr0 --match state --state ESTABLISHED,RELATED --jump ACCEPT' exited with non-zero status 1 and signal 0: iptables: No chain/target/match by that name 17:53:42.153: error : networkAddMasqueradingIptablesRules:615 : failed to add iptables rule to allow forwarding to 'virbr0': Invalid argument 17:53:42.354: warning : qemudStartup:1067 : Unable to create cgroup for driver: No such device or address 17:53:42.372: warning : lxcStartup:1755 : Unable to create cgroup for driver: No such device or address 17:53:43.259: warning : qemudDispatchSignalEvent:385 : Shutting down on signal 2 -~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~- libvirtd keeps running, however it does not open ANY new ports to listening state. Extract from /usr/local/etc/libvirt/libvirtd.conf : (full conf here: http://pastebin.com/f6e0f572) listen_tls = 1 listen_tcp = 1 /usr/local/var/log/libvirt has 3 empty directories: {lxc,qemu,uml}, so nothing logged. xen:/# virsh list shows my current running domains, so looks like libvirt is fine. I have compiled XEN and libvirt from source (0.7.4, then upgraded 0.7.5, got same errors on both versions). Additional information: I am running three guest domains, all bridged to eth0 (peth0 ethernet card -> eth0 bridge -> vifs), from xend-config.sxp: (network-script network-bridge) Debian lenny Linux xen 2.6.18.8-xen0 #1 SMP Fri Nov 27 18:17:01 EET 2009 x86_64 GNU/Linux (here is kernel config: http://pastebin.com/f393c78f0) Note: I compiled iptables as a module manually, however without IMQ support, since it failed to compile. I have installed Xen 3.4.2, however virsh thinks it's 3.4.0 -~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~- virsh # version Compiled against library: libvir 0.7.5 Using library: libvir 0.7.5 Using API: Xen 3.0.1 Running hypervisor: Xen 3.4.0 -~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~--~*~- Any suggestions how to properly start libvirtd, pointers to other related mailing-lists or forums are very welcome.
