Adding Nauman - he had a similar problem starting a vm: libvirtError: Child quit during startup handshake: Input/output error and we were unable to solve it. Nauman - Please try the solution Dafna suggested below: /usr/lib/systemd/systemd-vdsmd reconfigure if that doesn't work try: /usr/lib/systemd/systemd-vdsmd reconfigure force I am not sure that you have the same issue, but it might be worth it to try. Also you can check in the qemu log of the vm if you see something like this:
libvirt: Lock Driver error : unsupported configuration: Read/write, exclusive access, disks were present, but no leases specified 2014-01-03 13:52:11.306+0000: shutting down

VMs start and can be migrated. Thanks a lot for your help - and I'll stay with the node iso image :)

Redirecting to /bin/systemctl reconfigure vdsmd.service Unknown operation 'reconfigure'. /usr/lib/systemd/systemd-vdsmd reconfigure force
... seems to me, I should get rid of the ovirt-node iso installation and move to a rpm based install?

can you run: service vdsmd reconfigure on the second host?

Dafna,
yes, the VM starts on the first node, the issues are on the second node only.
/etc/libvirt/qemu-sanlock.conf is identical on on both nodes:
auto_disk_leases=0 require_lease_for_disks=0
yum updates reports "Using yum is not supported"...

ok, let's try to zoom in on the issue... can you run vm's on the first host or do you have issues only on the second host you added? can you run on both hosts? # egrep -v ^# /etc/libvirt/qemu-sanlock.conf
can you run yum update on one of the hosts and see if there are newer packages?
Thanks,

ignore the link :)
so searching for this error I hit an old bug and it seemed to be an issue between libvirt/sanlock.
https://bugzilla.redhat.com/show_bug.cgi?id=828633
are you using latest packages?

actually, looking at this again, it's a libvirt error and it can be related to selinux or sasl. can you also, look at libvirt log and the vm log under /var/log/libvirt?
