Ovirt attach serial port on VM
by Alex K 27 Sep '18

27 Sep '18

Hi all, I have a serial port on one of the servers where the guest VM is running. setserial -g /dev/ttyS0 /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 I wanted the serial port to be connected at the VM, so as the VM to be able to use directly the serial port of the server. Thus I went at host devices to add the port but I am not able to find it, as the serial port is not listed at PCI devices. I recall that on plain KVM one could be able to attach such a serial port at a guest VM. Has anyone been able to attach a serial port to a guest VM woth ovirt? (I am running 4.2.5) Thanx, Alex

moving disks around gluster domain is failing
by g.vasilopoulos＠uoc.gr 25 Sep '18

25 Sep '18

Moving disk from one gluster domain to another fails, either with the vm running or down.. It strikes me that it says : File "/usr/lib64/python2.7/site-packages/libvirt.py", line 718, in blockCopy if ret == -1: raise libvirtError ('virDomainBlockCopy() failed', dom=self) I'am sending the relevant piece of log.. But it should be a file copy since it's gluster am I right?.

Live Migration broken in 4.2.6 under OVS/OVN networking
by Davide Butti 25 Sep '18

25 Sep '18

Hello; despite many tests and tentative adjustments, I'm currently unable to live migrate VMs on oVirt 4.2.6. The vdsm.log contains a "failed to migrate" error, that points to an attempt to access a non-existent network port "TestOne". This is in fact the name of the (externally defined) network, and isn't anywhere to be seen as OVS port. 2018-09-24 14:32:57,059+0000 ERROR (migsrc/4c0255b5) [virt.vm] (vmId='4c0255b5-0f52-4da7-ac97-d54d815cd6ab') Cannot get interface MTU on 'TestOne': No such device (migration:290) 2018-09-24 14:32:57,793+0000 ERROR (migsrc/4c0255b5) [virt.vm] (vmId='4c0255b5-0f52-4da7-ac97-d54d815cd6ab') Failed to migrate (migration:455) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 437, in _regular_run self._startUnderlyingMigration(time.time()) File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 509, in _startUnderlyingMigration self._perform_with_conv_schedule(duri, muri) File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 587, in _perform_with_conv_schedule self._perform_migration(duri, muri) File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 529, in _perform_migration self._migration_flags) File "/usr/lib/python2.7/site-packages/vdsm/virt/virdomain.py", line 98, in f ret = attr(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 130, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 92, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1746, in migrateToURI3 if ret == -1: raise libvirtError ('virDomainMigrateToURI3() failed', dom=self) libvirtError: Cannot get interface MTU on 'TestOne': No such device The setup was previously working under OVS, and I have "migration_ovs_hook_enabled = true" under /etc/vdsm/vdsm.conf Do I need to change anything? Is this supposed to work in the first place? Many thanks for your help, have a nice day
