13.1 xen still broken?

English Virtualization
1

Had a problem with a 12.1 machine a while back, so I have been trying to upgrade it to fix. The new Virtualization Repository is setup and the system has been updated.

  • VMM refuses to start, throwing the error:

Failed to connect socket to ‘/var/run/libvirt/libvirt-sock’: No such file or directory

Now, that’s REALLY weird, as there IS no libvirt-sock in that location:

ll /var/run/libvirt/

total 0
drwxr-xr-x 2 root root 40 Jan 17 14:30 libxl/
drwx------ 2 root root 60 Jan 17 14:31 network/

[libxl is empty]

  • The Xen kernel appears to be running:

ps ax | grep xen

65 ? S 0:00 [xenwatch]
66 ? S 0:00 [xenbus]
729 ? Ss 0:00 avahi-daemon: running [xen.local]
792 ? S< 0:00 [xen_pciback_wor]
986 ? S 0:00 /usr/sbin/xenstored --pid-file /var/run/xenstored.pid
1159 ? SLl 0:00 /usr/sbin/xenconsoled --pid-file=/var/run/xenconsoled.pid
1245 ? Sl 0:00 /usr/lib/xen/bin/qemu-system-i386 -xen-domid 0 -xen-attach -name dom0 -nographic -M xenpv -daemonize -monitor /dev/null -serial /dev/null -parallel /dev/null -pidfile /var/run/qemu-dom0.pid

  • libvirtd does not respond to any service commands:

service libvirtd status

libvirtd.service - Virtualization daemon
Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled)
Active: inactive (dead) since Fri 2014-01-17 14:45:29 CST; 3s ago

Jan 17 14:45:28 xen systemd[1]: Started Virtualization daemon.
Jan 17 14:45:29 xen libvirtd[4354]: libvirt version: 1.1.2

Even though it appears to start, it does not.

  • The only entries in libxl-driver.log are cache misses:

xc: debug: hypercall buffer: total allocations:18 total releases:18
xc: debug: hypercall buffer: current allocations:0 maximum allocations:4
xc: debug: hypercall buffer: cache current size:4
xc: debug: hypercall buffer: cache hits:13 misses:4 toobig:1

I would like to get this box running, … any suggestions would be appreciated.

Thanks!

Just used Yast to install Virtual Machine Manager on a virgin 13.1 installation, … service livbvirtd status shows it is running, but virt-manager does not show a connection available! Is there any hope of getting Virtualization running on 13.1?? What’s going on?? Thanks! Lee

Hello,

I’m on OpenSuse 13.1 (migrated from 12.3) with the XEN kernel from tumbleweed.
Libvirtd and VM are running correctly:

ps -ef | grep vir
root      2442     1  0 janv.16 ?      00:00:04 /usr/sbin/libvirtd --listen
root     15273     1  2 20:44 ?        00:00:05 python /usr/share/virt-manager/virt-manager.py

Do you have started qemu?

As far as i remember I had to create a qemu user so that qemu starts correctly

id qemu
uid=488(qemu) gid=124(qemu) groupes=1(bin),120(libvirt),124(qemu)

ps -ef | grep qemu
root      1221     1  0 janv.16 ?      00:00:19 /usr/lib/xen/bin/qemu-system-i386 -xen-domid 0 -xen-attach -name dom0 -nographic -M xenpv -daemonize -monitor /dev/null -serial /dev/null -parallel /dev/null -pidfile /var/run/qemu-dom0.pid
root     15338     1  1 20:45 ?        00:00:04 /usr/lib/xen/bin/qemu-system-i386 -xen-domid 1 -chardev socket,id=libxl-cmd,path=/var/run/xen/qmp-libxl-1,server,nowait -mon chardev=libxl-cmd,mode=control -xen-attach -name Samba -vnc 127.0.0.1:0 -k fr-be -M xenpv -m 1025

I start the VM via Yast.==> virtual manager ==> connect ==> open VM ==> connect to VM
