Re: [libvirt] [PATCH] qemuDomainGetPreservedMounts: Fetch list of /dev/* mounts dynamically

Hi Michal ☹ Nothing changes with your patch(without workaround and with /dev/mqueue mounted) root@s2600wt:~/linux# cat /proc/mounts | grep mqueue none /dev/mqueue mqueue rw,relatime 0 0 root@s2600wt:~/linux# vim /etc/libvirt/qemu.conf root@s2600wt:~/linux# grep namespace /etc/libvirt/qemu.conf # To enhance security, QEMU driver is capable of creating private namespaces # for each domain started. Well, so far only "mount" namespace is supported. If # devices entries throughout the domain lifetime. This namespace is turned on #namespaces = [ "mount" ] #namespaces = [] root@s2600wt:~/linux# virsh start kvm02 error: Failed to start domain kvm02 error: An error occurred, but the cause is unknown Attach kvm02.log, but seems nothing debug information helpful. 2017-01-06 02:47:37.544+0000: 74279: debug : virCommandHandshakeChild:435 : Notifying parent for handshake start on 26 2017-01-06 02:47:37.544+0000: 74279: debug : virCommandHandshakeChild:443 : Waiting on parent for handshake complete on 27 libvirt: error : libvirtd quit during handshake: Input/output error Best Regards Eli Qiao(乔立勇）OpenStack Core team OTC Intel. -- On 05/01/2017, 10:46 PM, "Martin Kletzander" <mkletzan(a)redhat.com&gt; wrote: On Thu, Jan 05, 2017 at 02:41:02PM +0100, Michal Privoznik wrote: Works for me, ACK. I still wonder whether we should mark the mounts as slaves. I was also wondering if there are multiple sub-subtrees and from the code it looks like it will 'just work'. Nice. Martin
