Hi, I had a question on IRC regarding sysprep/sealing of Windows VMs and use in Pools. Basically, if you follow the Quick Start Guide, it says to seal the VM and shut it down before making the Template. My problem with this is that when you start a VM from the Pool, it takes forever to unseal - i.e. to repersonalize itself. That's a bad experience from a VDI perspective - you want the user to get a desktop they can start using ASAP. Itamar responded to me directly via e-mail: > bobdrad: on your question of windows VMs from pool - you can start > them once with an admin for the sysprep to happen, then shut them down. > admin launch of VMs doesn't create a stateless snapshot and > manipulates the VM itself. This raises some questions. I'd love to understand this better. He's asked me to cross this conversation onto the Users list now. 1. My understanding is that a Pool clones VMs on demand from a template. So how does the admin "launch" the template? I thought the only way to exercise a pool is from the User Portal. Is it sufficient to do that as Admin? I thought the persistence only came when launching a VM from the Admin Portal. 2. My understanding of "sealing" a system is that this depersonalizes it - e.g. removes hostname, prepares network for reinitialization, etc. And that the next time the system boots up it re-personalizes. So if one were to restart it, even as admin, this would reverse the sealing process, which would seem to make sealing in the first place pointless. What am I missing? At the moment I don't see the point of sealing a VM before putting it into the Pool (assuming you're using DHCP, anyway). What happens if you don't? Thanks, Bob P.S. I note the behavior of Fedora vs RHEL 6 is quite different in this regard. If you follow the "sealing" process on the Quick Start page for Fedora it seems to have no visible effect, but on RHEL 6 it puts you through a re-personalization dialog which is rather extensive (and again, not really suitable for VDI use).

[Users] Trusted Pools and CentOS 6 packages
by Gianluca Cecchi 15 Nov '13

15 Nov '13

Hello, based on http://www.ovirt.org/Trusted_compute_pools_deployment#Provision_White_List_… The commands of kind: bash_oat_cert .. bash oat_oem ... are to be run on hypervisor host side, correct? Where can I find these packages for CentOS 6? Thanks in advance Gianluca PS: I took the time to correct a typo in client section where it said "Yum Install oat server package from fedora19 repository" instead of "Yum Install oat client package from fedora19 repository"

[Users] Change data domain
by Juan Pablo Lorier 15 Nov '13

15 Nov '13

Hi, I'm changing the master domain to a new added one. I've placed the old in maintenance and ovirt made the change of master to the new one. The thing is that now that I have both active, I get this error: Sync Error on Master Domain between Host Dell2 and oVirt Engine. Domain: IBM3300 is marked as Master in oVirt Engine database but not on the Storage side. Please consult with Support on how to fix this issue. How can I fix this? Another thing, is there a way of having two iscsi data domains mirrored? To have a sort of high availability in the data domains. Regards,

[Users] Problems with first time oVirt installation
by Lindsay Mathieson 15 Nov '13

15 Nov '13

Hi all - trying to evaluate ovirt and having real problems with getting a self contained install running. I've followed the Quickstart guide at: http://www.ovirt.org/Download word for word using a fresh CentOS 6.4 install with all updates applied on a Intel based PC with 8GB Ram and two nics. It seems to all go well but when I get into the web interface, none of the storage is initially visible, neither the ISO_DOMAIN nor the local storage. Oddly if I refresh the browser (firefox & chrome) while on the storage page the ISO_DOMAIN appears but can't be attached to a datacenter - "None Available" If I go into the host page the host is there but not finished configuring. The network setup is unfinished, the management interface is not attached to a NIC. If I attach it to the active nic (NIC 0) it throws an exception on Save. I can attach it to nic 1 but its not actually hooked up to anything. I have successfully installed and run proxmox on this pc, so don;t think there are hardware problems. On a related note - I've also been trying to test ovirt at home, which means running it on KVM (setup with virt-manager). CentOS installs fine but on reboot just goes to a black screen with the hour glass. If anyone has suggestions on how to get past that it would help my test config a lot :) Host machine is Kubuntu 13.10. Thanks, -- Lindsay

[Users] Gluster RDMA support
by Murphy-Olson, Daniel E. 14 Nov '13

14 Nov '13

Hi all, I'm trying to configure a gluster storage pool over RDMA protocol. I created the volume by hand, because RDMA is disabled in the volume creation interface due to a patch ~18 months ago. After the manual creation of the volume, it displays bot protocols as being configured.. However, in the XML configuration that is generated for libvirt, ?protocol=rdma is not appended to the path. Is there some template I can edit to add that, or is it buried in the code somewhere? I cannot seem to find where the vsdm clients are getting the url for the gluster volume. Thanks! ---- Daniel Murphy-Olson Systems Administrator Mathematics & Computer Science Division Argonne National Laboratory 630-252-0055

[Users] Failed to start JBoss AS
by Bob Doolittle 14 Nov '13

14 Nov '13

Hi, I had a working engine, using 3.3.0 on Fedora 19. I rebooted my engine, and JBoss AS won't come back up. I get the attached errors from server.log. Has anyone seen this before? Any suggestions on how to recover? How I got here: I had a working Engine (mach1 F19) and Host (mach2 F19), but needed to play some musical chairs with my hardware to utilize a 3rd machine (mach3 RH6). My goal is to have mach2 become Engine, and mach3 Host. I did the following: 1. Created an NFS share on mach3, and used it as NFS Export Storage from mach2. 2. Exported my VMs and templates to the Export storage. 3. Removed mach2 from my Datacenter 4. Shut down mach1 5. Installed fresh F19 on mach2 (my old host), and installed Engine 3.3.0 on it 6. Added mach3 as Host 7. Imported my VMs and Templates from the Export Storage At this point all looked well. I rebooted mach2, but it won't come back up. I'd appreciate any insight. Thanks, Bob
