[opensuse-virtual] libvirtd, qemu+ssh and polkit: internal error: received hangup / error event on socket?
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, maybe this is an old issue, but I am just starting to set up my machines with libvirt and qemu-kvm, and tried using a remote connection. I already changed the following lines in libvirtd.conf: unix_sock_group = "libvirt" unix_sock_rw_perms = "0770" auth_unix_rw = "none" I made my user a member of said group 'libvirt'. And I restarted both libvirtd and polkit. I can connect as local user via virsh -c qemu:///sytem without a password prompt. I can also ssh into the remote host with my ssh key without problems. Trying from another machine (say hostname HOSTX, username testuser) with virsh -c qemu+ssh://testusers@HOSTX/system always results in
error: failed to connect to the hypervisor error: internal error: received hangup / error event on socket
I found not much information on this error, so I need your help. /var/log/messages says:

I am curious about the "disconnected by user" line, but I could not figure out what causes this line. I tried adding the libvirt rules to /etc/polkit-default-privs.local and all kinds of javascript stuff to /etc/polkit-1/rules.d/, but to no avail. Is configuring polkit necessary anymore? I am using Tumbleweed, which means libvirt* is 1.1.2-2.18.3.x86_64 and polkit is polkit-0.112-2.1.x86_64.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As this might be an issue in tumbleweed, I'll take this to the factory ml. Fullquote due to crosspost, follow-ups please to opensuse-factory I currently have no non-Tumbleweed machine, so I cannot test if this is tumbleweed-related. It seems that libvirt is not in tumbleweed, at least thats what http://software.opensuse.org/package/libvirt says. (Version I have is 1.1.2, and its from openSUSE current OSS Update repo. I cannot say if e.g. polkit are the cause here. Thanks in advance, Johannes On 24.03.14 21:49 Johannes Kastl wrote:

Now it works. I suddenly got prompted to accept the ssh host key of the target server, and it worked. The only thing I changed was to have a libvirt.conf for the user, to set some aliases and a default uri. Maybe that was it. Regards, Johannes - -- In the beginning there was nothing.

Unfortunately, you can't use polkit remotely. I think you are suffering the same problem I wasted time investigating several years ago http://www.redhat.com/archives/libvir-list/2010-November/msg00820.html Regards, Jim -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org
