VM with attached host USB device failed to run
by Дровалев Роман 18 Aug '17

18 Aug '17

Hello, Please help! Does anyone have a working USB forwarding in a virtual machine? If "YES", how did you solve this problem? If this problem is not solved, unfortunately, the ovirt will have to completely abandon. (( oVirt Engine Version: 4.1.4.2-1.el7.centos Thanks.

install of engine
by david caughey 18 Aug '17

18 Aug '17

Hi folks, I have installed the ovirt OS on 3 dl380's. It has been deployed with gluster and all is fine up to a point. When I try to install the engine it is trying to get out to the internet but unfortunately I am behind a proxy with strict rules, is there a way to point to a local copy of the engine using the GUI install or can I scp the iso over to the first node for local install, is there a particular partition where the iso should be stored. Any help appreciated, BR/David

oVirt Node with bcache
by FERNANDO FREDIANI 16 Aug '17

This is a multi-part message in MIME format. --------------4B191FE3792DDE5D00F7F478 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello I just wanted to share a scenario with you and perhaps exchange more information with other people that may also have a similar scenario. For a couple of months I have been running a oVirt Node (CentOS 7.3 Minimal) with bcache (https://bcache.evilpiepirate.org/) for caching a SSD with HDD disks. The setup is simple and was made for a prof of concept and since them has been working better than expected. This is a standalone host with 4 disks being: 1 for Operating System, 2 x 2TB 7200 RPM in software RAID 1 and 1 x PCI-E NVMe 400GB SSD which plays the caching device for both reads and writes. The VM storage folder is mounted as a ext4 partition on the logical device created by bcache (/dev/bcache0). All this is transparent to oVirt as all it sees is a /folder to put the VMs. We monitor the IOPS on all block devices individually and see the behavior exactly as expected: random writes are all done on the SSD first and them streamed sequentially to the mechanical drives with pretty impressive performance. Also in the beginning while the total amount of data was less than 400GB ALL read used to come from the caching device and therefore didn't use IOPS from the mechanical drives leaving it free to do basically writes. Finally at sequential IOPS (as described by bcache) are intelligently passed directly to the mechanical drives (but they are not much). Although bcache is present on kernel 3.10 I had to use kernel-ml 4.12 (from Elrepo) and I had also to compile the bcache-tools as I could not find it available in any repository.

Communication Problems between Engine and Hosts

This is a multi-part message in MIME format. --------------7A7A94A488D7D26C7D1B2EB5 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello. Yesterday I had a pretty strange problem in one of our architectures. My oVirt which runs in one Datacenter and controls Nodes locally and also remotelly lost communication with the remote Nodes in another Datacenter. To this point nothing wrong as the Nodes can continue working as expected and running their Virtual Machines each without dependency of the oVirt Engine. What happened at some point is that when the communication between Engine and Hosts came back Hosts got confused and initiated a Live Migration of ALL VMs from one of the other. I had also to restart vdsmd agent on all Hosts in order to get sanity my environment. What adds up even more strangeness to this scenario is that one of the Hosts affected doesn't belong to the same Cluster as the others and had to have the vdsmd restarted. I understand the Hosts can survive without the Engine online with reduced possibilities but can communicated between them, but without affecting the VMs or even needing to do what happened in this scenario. Am I wrong on any of the assumptions ?

VM with attached host USB device failed to run
by Дровалев Роман 16 Aug '17

16 Aug '17

Hello, I connected a USB to the VM, writes this error: VM Win2012 is down with error. Exit message: local variable 'device' referenced before assignment. I found this bug - https://bugzilla.redhat.com/show_bug.cgi?id=1261075 Does anyone have a working USB forwarding in a virtual machine? If "YES", how did you solve this problem? If this problem is not solved, unfortunately, the ovirt will have to completely abandon. ((
