[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

Hi, I used google chrome 17, Mozilla firefox and Knoquerer browser to access the ovirt-manager, but all of them say that browser is not supported. Can anybody help with the information about the supported browsers for oVirt manager UI. Thanks in advance :) -- Regards, Rahul ========================================================

[Users] Change virtual disk interface
by wdh＠dds.nl 01 Mar '12

I have serveral "old" KVM virtual images, all off them using virtio for networking and disks. Trying to import these into my EXPORT datastore ends up with an error: virt-v2v -i libvirt -o rhev -os 10.0.0.3:/nfs/export -n br0 PXE5-test PXE5.img: 100% [=====================================================] virt-v2v: WARNING: Unable to convert this guest operating system. Its storage will be transfered and a domain created for it, but it may not operate correctly without manual reconfiguration. The domain will present all storage devices as ide, all network interfaces as rtl8139 and the host as x86_64. virt-v2v: PXE5-test configured without virtio drivers. How can I avoid these errors? How can I fix this error. After restoring the image, I am able to change the network interface from rtl8139 to Virtio. However; I cannot change the disk. In the admin console going to Virtual Machines --> <virtual machine> --> Virtual Disks --> <disk> --> Edit gives a menu, but the only option I can change is "is bootable". Options like "Interface" are grey and cannot be modified.

[Users] Trying to understand oVirt terminology.
by Sharad Mishra 29 Feb '12

29 Feb '12

While reading oVirt Wiki and other related docs, I came across multiple terms that meant the same thing (at least to me). Please take a look and let me know where I am wrong. 1) Difference between RHEV and oVirt node - oVirt node has VDSM and libvirt whereas RHEV only has libvirt. 2) 'RHEV-M server' is same as 'oVirt Engine Mgmt Server' is same as 'oVirt Engine'. 3) 'oVirt API' is same as 'REST API' is same as 'RHEV-M API' which is same as 'oVirt Engine API'. 4) 'Host Agent' is same as VDSM 5) 'oVirt Node API' is same as VDSM API. Question ) Guest Agent is running on VM. How does it get installed there? Regards, Sharad Mishra

[Users] some ovirt questions
by hai wu 29 Feb '12

29 Feb '12

1. For ovirt, and future rhev, what's the recommended way going forward: ovirt node vs vsdm? 2. For ovirt, and future rhev, libvirt would be supported i think, what's the recommended way in terms of API going forward? libvirt API or REST API? I am not sure what's the difference between these 2. My understanding is libvirt might only be good for one physical host, and REST API would be good for the whole cluster, is this the case?

[Users] Remove and Add host does not work
by Deepak C Shetty 28 Feb '12

28 Feb '12

Hi, I had a host managed via OE, completely working fine. Was even able to create and run VMs off it. I tried removing the host from the OE (put host into maint. mode and then remove) and when i re-discover the same host, OE just keeps seeing it as Non-responsive. I am able to ssh into the host and see that none of the vdsm processes have been started. I tried doing "Confirm host has been rebooted" on the OE, did not help. I tried putting host into maint. mode and re-activating the host, just doesn't help I waited for ~45 mins thinking OE might connect to the host, start vdsm and get me the Up status but it failed. Do i need to manually start vdsm in such a scenario on the host ? Are there ways or methods to have OE forcibly start vdsm on the host ? thanx, deepak

Currently we handle standard platforms (ie- not the node), by using the all-in-one rpm which is currently in work. So when you add a host via the REST you may specify not to reboot it, and you should not specify power-management from properties, which will make sure fencing will not occur.
