Sorry, I mean "migration network" for moving live migration traffic. FDR infiniband much faster than 1Gb network which currently acts as migration network, vm network, display network, mgmt network, etc. Thanks, Douglas Duckworth, MSc, LFCS HPC System Administrator Scientific Computing Unit Weill Cornell Medicine 1300 York - LC-502 E: doug(a)med.cornell.edu O: 212-746-6305 F: 212-746-8690 On Fri, Aug 24, 2018 at 9:36 AM, Dominik Holler <dholler(a)redhat.com> wrote: > On Thu, 23 Aug 2018 13:51:39 -0400 > Douglas Duckworth <dod2014(a)med.cornell.edu> wrote: > > > THANKS! > > > > ib0 now up with NFS storage back on this hypervisor > > > > Thanks for letting us know. > > > Though how do I make it a transfer network?

Console to HostedEngine
by Daniel Menzel 24 Aug '18

24 Aug '18

Hi at all, we cannot access our hosted engine anymore. It started with and overfull /var due to a growing database. We access the engine via SSH and tried to fix that - but somehow we seem to have produced another problem on the SSH server itself. So unfortunately we can not login anymore. We then tried to access it via its host and a "hosted-engine --console" but ran into an internal error: cannot find character device <null> which I know from KVM. With other VMs I could follow the RedHat's advice to add a console (https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/ht…) but although I edited the hosted engine's profile those changes weren't applied - and after an engine restart even deleted again. That kind of makes sense to me, but limits my options. So my question is: Is there any idea how can I access the the console with my current limitations to fix the SSH server's problems and then hopefully fix everything? Regards Daniel

Re: losing ib0 connection after activating host

Hi Dominik Yes, the network-script was created by our Ansible role that deploys CentOS hosts. It pulls the IP from DNS then templates the script and copies to host. I will try this oVirt step then see if it works!

Upgrading librbd1 and librados2 for oVirt 4.2.x
by andreas.elvers+ovirtforum＠solutions.work 24 Aug '18

24 Aug '18

Hallo Group ! I am in need of upgrading librbd1 and librados2 for a oVirt 4.2.x cluster. The cluster was installed via node ng. Taking the repository for Ceph Mimic or Luminous will end in a dependency problem because liburcu-cds.so.1 is already installed as a more recent version provided by the oVirt repository. A hint on how to get a more recent versions of the above libraries would be very much appreciated. Thanks, - Andreas

HA VMs not starting automatically on another host after host crash.
by Eduardo Mayoral 24 Aug '18

24 Aug '18

Hi, Recently I have had 2 oVirt hosts (oVirt 4.2, CentOS 7.5) crash unexpectedly (not at the same time). Both seem hardware related. In both cases oVirt did detect the host as non responsive, did a fence on the hosts and set the VMs which were running on the host at the time as "Down". So far, so good. The hosts were on 2 different clusters. Both had Migration policy / resilience policy set to "migrate Virtual Machines". The VMs are not configured as "Highly available", but my understanding is that with that resiliency policy, this makes no difference. My (probably wrong) expectation, is that oVirt should have attempted to start the VMs in another host. It did not. A colleague started the VMs manually and they started with no further issues. So. How should I configure oVirt to try to start the VMs on another host when the physical host they are running in crashes? Thanks in advance! -- Eduardo Mayoral.

VM has been paused due to unknown storage error. - Only on NFS / EMC
by jeanbaptiste＠nfrance.com 24 Aug '18

24 Aug '18

Hello, I'm facing a strange issue on my OVirt Dev pool. Indeed, when I create high disk load a VM (kickstart installation or iozone test for example) , VM is paused due to storage I/O error. Problem is 100% reproducible, and is located only on NFS (v3 and v4) on my EMC VNXe3200 NAS's (I have a 10TB and a 20TB NAS) I have done test (simple iozone -a) with VM 1 vCPU / 2GB RAM and 2 disk (1*20GB + 1*10GB). Both VMs disk are placed into the same SAN / NAS for each test. Results are: - EMC VNXe3200 (10TB) NFSv3 => VM stopped after 10- 30s iozone lauch - EMC VNXe3200 (20TB) NFSv3 => VM stopped after 10- 30s iozone lauch - EMC VNXe3200 (10TB) ISCSI => No problem, iozone test finish, and performance are "standard" regarding load of the VNXe (60MB/s sequential Write for info) - EMC VNXe3200 (20TB) ISCSI=> No problem, iozone test finish, and performance are "standard"regarding load of the VNXe (40-60MB/S sequential Write for info) - NETAPP FAS2240 NFSv3 => No problem, iozone test finish, and performance are good (100MB/s sequential Write for info) - Freebsd10 NAS NFSv3 => No problem, iozone test finish, and performance are good regarding NAS conf (80MB/s sequential Write for info) I can't explain why I have an issue on NFS and I have not issue on ISCSI (on the same EMC VNxe3200...).

Update disk alias by using ovirtsdk4
by branimirp＠gmail.com 24 Aug '18

24 Aug '18

Hello list! I have been trying to rename a disk alias that defaults to "some_template_name-Disk1" to something more logical by using ovirtsdk4 (in my example to "vm2_disk_0"). On the list itself, I saw a couple of examples for older version of SDK. Basically, I am trying to create a VM and then update its properties, notably "alias" attribute that can be found in types.Disk. The first portion of the code works well (vm provisioning), but second one (alias update) does not, causing the TypeError exception. Obviously, I am doing something wrong here. I have spent most of the time trying to figure out how to actually do this. I would kindly ask for some hint. Thank you in advance! Regards, Branimir ******************************* # create a vm vms_service = connection.system_service().vms_service() vms_service.add( types.Vm( # --- vm name name='vm2', # --- vCpus cpu=types.Cpu( topology=types.CpuTopology(cores=2, sockets=1) ), # --- memory memory = 512*1024*1024, # -- oVirt cluster cluster = types.Cluster( name='cluster_1', ), # -- template to use template = types.Template( name='centos7-tmplt-compute-node-v1'), # -- boot device os = types.OperatingSystem(boot=types.Boot(devices=[types.BootDevice.HD])), ), ) # update the vm in terms of disk name vm = vms_service.list(search='name=vm2')[0] vm_service = vms_service.vm_service(vm.id) updated_vm = vm_service.update( types.Vm( disk_attachment = types.Disk(alias='vm2_disk_0') ) )
