ovirt-guest: Network device hanging shortly after startup (after Upgrade to 4.3.5)
by julius.kempa＠astelon.ch 06 Sep '19

06 Sep '19

We have a some old guests (SLES 10.4) which has been worked corectly till 4.2.7 (Manager + Host) After Upgrade to 4.3.5, we have got a network issue, that the gues network device, not depending on used device type, stopts to work after some seconds.... after about 15-20 pings device is hanging. Sometimes, in the first time after the device hungs up, the message "no buffer space available" comes from ping. Does someone knows a solution for it? greetings Julius

VM crushed and cant shutdown successfully,It always on the way to shutdown，even if I wait it for 10 hours；Everytimes I shoud to reboot the ovirt-node machine This comes up 4 times, It appes both on the ovirt-noe 4.3 and 4.2; This bug appers when my VM is running at high load（seems memory and disk's w/r） My storage domain is local on host; When the bug appers,it could cost my node's io,looks like the picture below；But sometimes it will not The vm's threading on the ovirt-node, the IO ratio is 100% Everytime the vm's process will change to defunct I can not kill it,I had to shutdown the ovirt-node on the engine website ,the vm's status always in the way to shutdown ,even if I wait for it for hours; It either failed or is shutting down and the "power off" cant shutdown the vm too. the vm's error below The ovirt-node's error below ---------------------------------------------------------------- The other infomation about my ovirt-node node-version： node hardware zhouhao(a)vip.friendtimes.net

Hi Sandro, Can the update work with 7.6 ? I'm asking because CentOS 7.7 is still building and unavailable.

Re: Any real experiences with nested virtualisation?

I guess you want to do something like this one : http://www.chrisj.cloud/?q=node/8 As Ovirt is upstream of RHV , I believe that RDO and Ovirt have almost the same integration as in the post. Still,such setup requires a lot of knowledge about KVM, oVirt and OpenStack.

Any real experiences with nested virtualisation?
by tonyppe＠gmail.com 04 Sep '19

04 Sep '19

I have ovirt 4.3.5 and Openstack hosts. There are 2 x openstack compute and 2 x ovirt hosts with hosted manager. I think i can simplify the management of this if I were to virtualise the openstack compute nodes as VMs on ovirt. I wanted to reach out here to gauge any other users experiences with it if at all. From the research I have done it looks like from the VM perspective, migration must not be allowed. Any info / comments / feedback appreciated. Regards,

Re: Cannot Increase Hosted Engine VM Memory
by Dionysis K 04 Sep '19

Now i noticed another strange i deactivated the memory balloon option from the VM hosted engine and tried to update the values again with the same memory it still keeps the value of memory size at 5120 while the value of physical memory guaranteed it changed to what we desire at the 8192 value and then the error appears again in the vm engine i ckecked the engine log file it shows the same errors! is there are other logfile locations that can give us any clues ?

iSCSI Multipath/multiple gateways
by dan.poltawski＠tnp.net.uk 04 Sep '19

04 Sep '19

My iSCSI target (ceph-based) has multiple gateways, I’d like to ensure my hosted storage is aware of these such that each gateway can be rebooted for maintance without impacting service. What is the appropriate way to configure this so that each host knows of the multipath configuration? I do not have multiple network paths, just multiple gateways on the same network, so I think the multipath UI tool isn’t the way to do this. Any help/docs pointers appreciated. Regards, Dan
