Re: [libvirt-users] LXC Memory Limits wont work

This isn't unique to libvirt LXC containers - in fact any command that is runnning in a cgroup with memory controller limits applied will see the same behaviour. Apps can't assume that 'free' reflects the amount of memory that is available to them. Instead they need to look at cgroups memory controller that they are placed under (/proc/self/cgroups tells you where) I think this is not completely true... I had a similiar problem in the past, and I could get it fixed by using e.g. this in the domains XML: 4194304 4194304 4194304 `free` then reports the correct values. Maybe you can give that a try @Markus Raps? Of course make sure to check out the documentation[1] of these config elements to make sure you really want what they do.

Re: [libvirt-users] Libvirt newer than 2.1.0 doesnt start up
Hi all, thanks so far for your time and ideas. Please find the gdb output and also the debug-output of libvirt (as requested by Michal Privoznik and Laine Stump) here: https://paste.xinu.at/m-gPSHl/ On 10/19/2016 01:58 AM, Michal Privoznik wrote: > Those "Network is already in use by interface virbr1" error messages > worry me.

If so, what's their content? Laine was already correct about that, this error message only appears when I manually try to restart libvirt after it already hung up. Maybe I should've made that more clear. Additionaly, no, there are no files in that directory, also I am pretty sure that I only got one instance of libvirt running According to the GDB log, the libvirt process is endlessly iterating over [1]. Any ideas what could be wrong?

[libvirt-users] Libvirt newer than 2.1.0 doesnt start up
Hi all, I have some problems with libvirt >2.1.0 (so 2.2.0 and 2.3.0): I have a working environment using libvirt 2.1.0 with 1 domain (called "mail") and one network (called "default6"), both are autostarted. I have no problems with this environment using libvirt 2.1.0, everything works great. But after (testwise) updating to libvirt 2.2.0 or 2.3.0, libvirt doesn't start up anymore. Some investigations showed that apparently my "default6" network is the problem. Libvirt is starting correctly after disabling all autostarts. When I then virsh' into the system daemon and type "net-start default6", then nothing happens and that command just hangs infinitely. Further information, relevant log entries and e.g. the used default6.xml configuration file can be found here, as I first thought it would be a configuration error from my side: https://bbs.archlinux.org/viewtopic.php?pid=1653221 Do you maybe have an idea what could be going on? Or do you maybe need more information, and if yes, which exactly? Thanks in advance Regards Rene ___ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
