[Users] RHEL 5.x on oVirt - high CPU on KVM-host
by Winfried de Heiden 03 Mar '12

03 Mar '12

Running both CentosOS 5.x and RHEL 5.x with all te latest patches gives a rather high CPU-load on the KVM-host, even when the machine is doing nothing. On the virtual server CPU-load is almost 0%. Installingen ktune and chaning the I/O scheduler to cfq gives a small change, CPU-load drops from apr. 26% to 19%. Adding devider=10 to the kernel parameters gives no improvement. Both nic and disk use virtio. It seems to be a kernel problem (there numerous thing to find on the internet) but anyone knows a solution? Winfried

Hi Vang and All. I build this rpm's for testing oVirt in CentOS 6.2, and it's working in my test environment. Today, I checked engine installation on fresh (but updated) CentOs 6.2 without problem. You can try to cleanup ovirt (engine-cleanup) remove all ovirt, vdsm and jboss packages (yum remove ovirt* vdsm* jboss*) clean yum cache and install ovirt-engine again. 03.03.2012 2:01 пользователь "Fong Vang" <sudoyang(a)gmail.com> написал:

[Users] using virt-v2v
by Dominic Kaiser 02 Mar '12

02 Mar '12

Got this error on a Fedora 16 box : virt-v2v: Installation failed because the following files referenced in the configuration file are required, but missing: /usr/share/virtio-win/drivers/i386/Win2008 What is this? Fedora does not have a virtio-win package but has an .iso. Does libguestfs take care of this need? Do we just need to put the .iso somewhere to meet this need? -- Dominic Kaiser Greater Boston Vineyard Director of Operations cell: 617-230-1412 fax: 617-252-0238 email: dominic(a)bostonvineyard.org

Re: [Users] Can anyone help? Spice not connecting - I have spice-xpi installed.
by Morgan Cox 02 Mar '12

02 Mar '12

Hi I have decided to bite the bullet and re-install everything,.... Can someone check and see if this idea seems like it will work... I will have 3 servers - 1. Ovirt engine (Lan address + external address) : name - frontend.server.com - 2. Storage server - debian NFS server (LAN address only) : name - storage1.server.com - 3. Ovirt node (from the node .iso) - I will set up Ovirt on an enternal; IP: name - node1.server.com In order to get the best speed (i.e by using LAN address's) I shall add the 2nd LAN interface on the node as a LAN address - (So it can comminicate with the storage node) .. Should I add the LAN address's of the ovirt node and storage on the frontend to /etc/hosts (i.e not the external IP - 10.0.0.x) ? Or will cause issues (like before) - I want it to send as much traffic via the LAN rather than external network (for speed) (also shall I add the frontend / storage to /etc/hosts on the node ?) Any ideas will be welcomed.

[Users] Can anyone help? Spice not connecting - I have spice-xpi installed.
by Morgan Cox 01 Mar '12

01 Mar '12

Hi I have been trying for hours to install a vm in Ovirt and having no joy., Spice is not working - I just get a black popup window I am connecting from a Fedora16 desktop - I have spice-XPI installed. can see 'press Shift+f12' to release mouse.... etc. My setup :- I have a 3 server setup - 1. Ovirt engine (Lan address + external address) - 2. Storage node - NFS server (LAN address and external address) - 3. Ovirt node (from the node .iso) - only LAN address The Engine server is a default FC16 install. the node is from the ovirt node .iso. I don't think its firewall related - I tried disabling firewalls on all servers. Once I try spice the icon is greyed out afterwards. In IRC it was suggested to run Bind from server 1 - I have done that and added DNS entrys in the LAN range for all 3 servers - all 3 servers are using bind from server1 as their only nameserver in resolv.conf I am trying to connect from my Fedora16 Desktop When I try to connect I see in /var/log/messages Mar 1 19:34:43 fedora16 spice: Warning: failed to connect: Connection timed out (110) Any ideas how to investigate this further. I am dying to test out a VM but with no spice I am presently unable to... Any ideas will be welcomed - i'm 1/2 thinking about re-installing with all external ips (but that will make transfer speeds slower..)

[Users] Can someone help me with moving a windows server 2008 to ovirt?
by Dominic Kaiser 01 Mar '12

01 Mar '12

So I have been looking at how to move windows 2008 and R2 servers from vmware esxi4 over to ovirt. I moved my Linux servers over with clonezilla. But windows needs a sysprep and generalize not to mention uninstalling vmtools and vmware drivers. I have done this. I then use clonezilla to put the image onto a thinprovisioned drive on ovirt. It starts to boot then blue screen of death. Am I missing something other than syspreping the windows machine and uninstalling the vmware drivers? Also is there a better way? P.S. Also I have ovirt up in a production envirenment and is running rock solid for the past month great job guys!

[Users] spice client support for windows
by sawan k r 01 Mar '12

01 Mar '12

Hi, I was reading on deploying spice on ovirt here - http://www.ovirt.org/wiki/Testing/Spice There is specific line there that says - A Linux client machine with spice client and spice xpi installed (packages spice-client and spice-xpi in Fedora/RHEL). It's not possible to connect to a guest from Windows client through Ovirt yet. Is above still valid? Can I use spice client on windows and connect to guest OS on KVM-ovirt? Thanks, Sawan

[Users] Q on ovirt datacentre and host storage types
by Deepak C Shetty 01 Mar '12

01 Mar '12

Hi, got few basic Qs in my mind. Appreciate a response. 1) Why is it that the data domains must be of the same type as that of datacentre ? What is the goal behind having this constraint ? It seems useful to have a datacentre w/o having any storage restrictions.. i should be able to add hosts w/o worrying abt the storage types... why is it not so... looking to understand the reason behind this design decision. 2) If i have a set of host systems all connected to shared FC storage, is there a way for me to configure LUNs exclusively for each host, meaning have ability to control what LUN each hosts sees ? Can this be done using oVirt today ? My understanding is that this cannot be done via ovirt, zoning of LUNs to host has to be done separately and not via ovirt, is that correct ? 3) If i have to create and run 1000 VMs (say), how can i automate that using ovirt, what is the best way to do that ? thanx, deepak
