I believe the problem here is that (1) does not pass an auth handler. ie. it calls virConnectOpenReadonly, not virConnectOpenAuth. It's my understanding that virConnectOpenReadonly bypasses the policy kit and SASL stuff, but Dan Berrange (CC'd) will be able to tell me if I'm correct about that.

Hi, We are hitting a deadlock on libvirt on 0.9.4 version. Can someone help us ? 1) Is there any way to specify timeout for all the calls made by libvirt especially virConnectOpenReadOnly 2) Does virCommandRunAsync always fork a new process ? gdb) bt #0 0x00007fc17b53ce6e in __lll_lock_wait_private () from /lib64/libc.so.6 #1 0x00007fc17b4e3f2d in _L_lock_2164 () from /lib64/libc.so.6 #2 0x00007fc17b4e3ce7 in __tz_convert () from /lib64/libc.so.6 #3 0x00007fc16e4bfdab in vi...

Hello, I'm running into an issue using the 'virt-df' command when SASL is enabled in libvirt. I'm running version 1.26.5 of libguestfs on an Ubuntu 14.04 OS. I'm running 'virt-df' for all guests at one time, not specifying a domain or image to use. I was expecting a SASL authentication prompt but to no avail. Below is a sample run: root@all-in-one:~# virt-df -P 15

Hi, When trying to connect the HyperVisor from a binary having setuid bit set , then I got following error: Unable to perform virConnectOpenReadOnly function error(internal error: libvirt.so is not safe to use from setuid programs) My test software config is the following : -rwsr-xr-x. 1 root root 3374956 Feb 4 13:45 test As this test software needs S bit to be able to access O.S. metrics counters , how may I use it to retrieve KVM metr...

Hi everyone: I am just a new user to libvirt. I installed libvirt as: ./configure make sudo make After that I run the program in the development guide. But it seems that the program is stuck in the function of virConnectOpenReadOnly. When I tried the command: virsh list --all, it is also stuck. So could anyone tell me what's wrong with this?

Hi, I found an answer : Use virConnectOpenAuth() instead of virConnectOpenReadOnly(). As my piece of code is running silently (without user connected) , by using virConnectOpenAuth() , is it possible to avoid to prompt user to get user /password ? Thx.

Yes it is. You basically need just to pass a callback that will supply credentials to libvirt. Does not matter...

I''ve tried connecting with both virConnectOpen() and virConnectOpenReadOnly(). I don''t see any obvious error messages when running libvirtd -- verbose, other than the one above, which shows up on machine #1. There are no obvious error messages in libvirtd --verbose on machine #2. I checked /var/log/xen/xend.log and xend-debug.log, but didn''t see a...

libguestfs usually needs qemu. However it only requires an emulator for the same architecture, not for all architectures. libvirt-daemon-kvm pulls in qemu which pulls in emulators for all architectures, as well as a bunch of other stuff we don't need at all like network interface support and nwfilter. There are no Fedora TCG-only arches, so drop the conditional section. I also made support
