windows remote-viewer vs. linux vm: strange keyboard problem
by Uwe Laverenz 03 Nov '17

03 Nov '17

Hi all, I have the following strange problem with virt-viewer 5.0 and 6.0 on Windows 10: when I connect to Linux VMs running on a OVirt 4.1 cluster it sometimes is not possible to use e.g. "AltGr + q" to get the "@"-sign or "AltGr+8" for "[" on my german keyboard. It seems to be a problem only when I use a dual screen setup with Linux VMs. It is possible to get it working by just moving the mouse to the top center of the screen until the remote-viewer panel shows up. After this the keyboard works for a short period of time until I work on the other screen. I tested CentOS 7,CentOS 6 and Fedora 26 VMs. Windows 7 VMs do not seem to show this problem, so I'm not sure if it is a problem with virt-/remote-viewer, OVirt/qemu or the Windows 10 client. Does anybody else see this behaviour? What would the best place for a bug report, OVirt and Spice/virt-viewer are separate teams, right? thanks in advance, Uwe

Sync two Nodes
by Jonathan Baecker 02 Nov '17

02 Nov '17

Hello everybody, I would like to sync two nodes, but I want that only one node runs permanently. Only once a week or a month I want to start the second node and sync them again, if this is necessary. What you would recommend for this scenario? oVirt have a HA functions, what I could use, but I thought oVirt brings then maybe errors when one node is always off. I'm wrong here? Or is there other options what works better? Have a nice day! Jonathan

Italian translation
by Sandro Bonazzola 02 Nov '17

02 Nov '17

Hi, looking at https://translate.zanata.org/iteration/view/ovirt/ovirt-4.2 I see Italian translation dropped under 80% for 4.2 after yesterday update. If you have some time and know Italian, it's a good time for contributing translations.

oVirt Node 4.1.6 on IBM x3650 M3
by Jon bae 02 Nov '17

02 Nov '17

Hello everybody, I would like to install oVirt Node on a IBM Machine, but after the installation it can not boot. I get the message: "/boot/efi/..." file not found I try many different things like turn of uefi options in bios etc. but with no effect. Now I figure out that when I install full CentOS 7.3 from live DVD it just boot normal. Is there any workaround to get this to work? Regards Jonathan

VM resource allocation and IO Threads
by Gianluca Cecchi 02 Nov '17

02 Nov '17

Hello, can anyone give any pointer to deeper information about what in subject and the value for "Num Of IO Threads" configuration, best practices and to-be-expected improvements? I read also here: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/ht… but in some points it seems not so clear to me: eg: If a virtual machine has more than one disk, you can enable or change the number of IO threads to improve performance. but also Red Hat recommends using the default number of IO threads, which is 1. There is also a note about deactivation and activation of disks: does it mean that even if I poweroff the VM and change its config I have to make this step after? Anyone has run benchmarks? Does it make sense if my VM has 3 disks to configure 6 IO threads for example? Do IO threads map to SCSI controllers inside the guest or what? Thanks in advance, Gianluca

can't use a iscsi target as a storage domain
by Nathanaël Blanchet 01 Nov '17

01 Nov '17

Hi, I give a try to 4.2 alpha andit seems to be a regression with registering a iscsi target as a storage domain. I'm able to login to the target, but when selecting the lun, clicking on OK does nothing else. I tried with the same lun on 4.1 and it is ok. -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr
