[FC22] testing oVirt 3.6.2 : Hot plug memory not working
by wodel youchi 01 Feb '16

01 Feb '16

Hi, I am using oVirt 3.6.2 on FC22 box, all-in-one installation, my purpose is to test it. I am using a simple Desktop : - one cpu core i5 3550 with 4 cores - 2x4 Go of RAM I installed a Centos 6x64 VM with all updates + ovirt guest agent. I tried to augment the memory from 1024 to 1536 (+512Mo) it didn't work I had to shutdown the VM for the change to take effect. Hot plug memory does it have something to do with the underneath hardware? or does it depend on the guest OS? or something else? Regards.

VDI non-persistant desktops

01 Feb '16

Hi all We're using RHEV 3.5.7 and have about 40 desktop VMs that are all clones from a single original. In the very beginning we used desktop pools but this was torn down when we started getting "The trust relationship between this workstation and the primary domain failed" error messages. We use DHCP for all desktops however every VM is defined on the DHCP server and unknown MACs are rejected. I'd like to revisit desktop pools but I'd like to know if other are using this and what their experiences have been. Kind of thing I'd like to know is - how is patching done - what is the performance like - what tuning if any is done on the desktops - GPO vs LPO Any comments? Thanks CC

No traffic on dummy interface
by Alan Murrell 31 Jan '16

31 Jan '16

Hello, I am running Ovirt 3.6.1 on CentOS 7.1 in a single server, hosted engine setup. I have created 10 dummy dummy interfaces names 'dummy_[0-9]'. Ovirt sees them, and in "Networks" for my cluster, I created 10 10 "internal" networks called 'Internal_[0-9]'. In the "Hosts" tab, in the "Network Interfaces" tab for my host, I assigned the 'dummy_*' interfaces tot he appropriate 'Internal_*' network (i.e., dummy_0 -> Internal_0, dummy_1 -> Internal_1, etc.) I have create two VMs and assigned a NIC interface on each attached to the 'Internal_0' network. I gave the interfaces on the gusts an IP int he same subnet, but they cannot talk to each other. When I try to ping one from the other, here is the response I get (public IPs redacted): --- START --- C:\Users\Administrator>ping 192.168.100.12 Pinging 192.168.100.12 with 32 bytes of data: Reply from 192.168.100.20: Destination host unreachable. Reply from XX.XXX.XX.XX: TTL expired in transit. Request timed out. Reply from XX.XXX.XX.XX: TTL expired in transit. Ping statistics for 192.168.100.12: Packets: Sent = 4, Received = 3, Lost = 1 (25% loss), --- END --- The IP of the PC I am pinging from is '192.168.100.20' I have been able to setup internal networks like this before, but seem to be missing something and I am not sure what? Here is what the dummy_0 interface shows when I run 'ip addr show': --- START --- 7: dummy_0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master Internal_0 state UNKNOWN link/ether 0e:a2:6b:54:1a:91 brd ff:ff:ff:ff:ff:ff --- END --- and Internal_0 looks like this: --- START --- 20: Internal_0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 0e:a2:6b:54:1a:91 brd ff:ff:ff:ff:ff:ff inet6 fe80::dc07:84ff:fe1b:60cb/64 scope link valid_lft forever preferred_lft forever --- END --- I am not sure what other info you need, so please do let me know. I did see this: <http://blog.duderamos.com/internal-isolated-networks-on-ovirt/> and except that I use 'dummy_*' instead of 'dummy*', my setup is the same. Thanks, in advance, for your help on this. Regards, Alan

VDI question: How much disk space used?
by Alan Murrell 30 Jan '16

30 Jan '16

Hello, I have a question about VDI and the use of a VM pool. Are the VMs that are part of the pool linked clones or full clones of the pool's template VM? Let's say my template VM has a HDD of 64GB, fully allocated. I create a VM pool that uses that template and the pool consists of 5 VMs. Do I need to have 64GB x 5 = 320GB of disk space available (actually 384GB, counting the template VM), or just the 64GB of the template VM + whatever temporary space is used by each VM for the temporary changes made while a user is using the VM? (I hope that makes sense?) Thanks! :-) Regards, Alan

After installing ovirt-hosted-engine-setup and it's dependencies on fedora 22, I can't get libvirtd to start using systemctl start libvirtd. When I pull up the journalctl -xe output, I see a number of entries saying: Jan 30 11:50:02 cedar.local libvirtd[1433]: Certificate /etc/pki/vdsm/certs/vdsmcert.pem usage does not permit key encipherment Not sure what to do here. Any help you could give would be appreciated! Thanks, Adam
