Hello, Since updating to libvirt 3.0 I am no longer able to create a virtual machine that is backed by LVM storage on my two Arch machines. This is the error in virt-manager: Unable to complete install: 'An error occurred, but the cause is unknown' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 88, in cb_wrapper

...e install: 'An error occurred, but the cause is unknown' This is likely a namespace bug. There are patches on the list to fix the issue [1], but lacking any review. Can you try applying them and see whether they fix your problem? 1: https://www.redhat.com/archives/libvir-list/2017-January/msg01127.html Michal

On a selection of boxes, ntpd running in Xen Dom0 reproducibly exhibits extermely high noise/jitter. Switching back to -default, non-xen kernel ntpd runs with very low jitter/noise. Question -- how can I ''tame'' ntpd noise & jitter when running in Dom0? Is the problem a config issue, or a bug? Already reported this downstream; everybody''s "stumped".
