Running VMware images on KVM host
Hello
Have anyone succeeded in running VMware/KVM mixed environment for VCL?
I'm having difficulties starting Windows 7 VMware images on KVM: the image would convert and load, but Windows gets blue screen.
I assume this is due missing virtio drivers while attempting to run Windows on KVM.
We also have VMware tools installed on Windows image, which may also contribute to the problem.
Thank you,

Re: Running VMware images on KVM host
Posted by Dmitri Chebotarov <dc...@gmu.edu>.
I think I found why some subroutines are not called.
In our environment we don't use Repository Path (under VM Host profile) and it looks like those subs only called when the setting is configured.
Ie. libvirt.pm:find_repository_image_file_paths() sub excludes .vmdk and returns proper -flat.vmdk file.
KVM.pm::update_windows_image() is also called on a condition when Repository Path is present in a VM profile.
What does Repository Path do and how is it different from Base Images (Virtual Disk Path)?
I use Virtual Disk Path (Base Images) and VM Working Directory Path for linked clones.
Both paths are on a shared NFS storage where all VM hosts have access.
Thank you,

The KVM.pm::update_windows_image should be doing this automatically. It
edits the registry of the offline Windows image to disable the VMware
Tools services and add the IDE disk entries. Please check if the
subroutine is working correctly in your environment.

Re: Running VMware images on KVM host

Andy, thank you for the info, it helped a lot...
I'm still working on details and testing, but at this point VCL loads VMware images on KVM hosts.
I needed to make some changes to Windows XP image to load it on KVM - this link has details -> http://pve.proxmox.com/wiki/Migration_of_servers_to_Proxmox_VE#Prepare_the_Windows_operating_system_2.
I did first two steps (remove vmware-tools & Enable IDE) on the VMware image and it loads on KVM just fine and everything appears working OK.
I've tried few versions of qemu/libvirt. Current configuration uses libvirt-1.0.3 and qemu-1.4.0 (latest) compiled on CentOS 6.3. I'don't know if I get the same results with older versions. xCAT helps to deploy KVM host image with custom changes to all blades - I don't need to build it multiple times...
I've tried Fedora 18, but for some reason HS21 server loosing keyboard after 30-40 sec, which makes it hard for initial server configuration.
If it wasn't for the keyboard problem (which I think is specific to my environment) then Fedora 18 would be my choice for KVM host, considering that oVirt only supports Fedora 18 at this point. Managing KVM from command line works, but GUI would be nice.
As for the linked clones, I found that copy-on-write image appears to works fine. It's very fast to create and barely uses any space at all.
I've changed 'qemu-img convert...' command in libvirt.pm to 'qemu-img create -b $source_file_paths_string -f qcow2 \"$destination_file_path\"' to clone KVM image. Also updated domain xml file for disk type.
Haven't tested it when updating/creating new image...
Thanks.

Check the commented out in KVM.pm::copy_virtual_disk. I left a bunch of of
code and comments in there while I was trying to figure out problems similar
to what you're describing. Some of it may be helpful.

Where did you edit? libvirt.pm::find_repository_image_file_paths() should
return every file with $image in the name except $image.vmdk. This is just
VMware's image metadata file. I haven't tested it but I think
$image-flat.vmdk should be returned. We are using the code as it is in
trunk. We are only converting from the images stored in the repository which
are in 2gbsparse format, not from images in the datastore in monolithic
*-flat.vmdk format.
BTW - I would advise against using the same datastore location for both VMware
and KVM images. I wrote the module with the assumption that the datastore
only contains KVM images. There may be conflicts if the KVM code finds
additional files in the datastore which contain the image name. Also assumed
is that when converting from vmdk to qcow2, the vmdk images reside in the
image repository in 2gbsparse format.

Aha, I don't think vmprofile.imagetypeid is set correctly. Change it from
vmdk to qcow2. This may be the cause of your overall problem. Try this first
and test if vcld properly converts the vmdk to qcow2.

Yes. This is what the code does when things are working properly. I don't
think KVM can run linked clones directly from a vmdk. It must be converted to
qcow2 first.

I'd like to know how to get things working on CentOS/RHEL as well. We mainly
use these and are only using Fedora because of the image conversion problems.

Hi
I've compiled qemu-1.4.0.
qemu-img in 1.4 still fails to convert $image.vmdk file, but works OK for $image-flat.vmdk files. To test it I changed the code in libvirt.pm to return $image-flat.vmdk for the file name. Did you have to adjust anything on your side for qemu-img to find $image-flat.vmdk to in $image.vmdk (1)?
The vcld.log has "copy on write virtual disk is not supported for the datastore image type: vmdk, creating full copy of master image file" message, I assume this means all VMware images running on KVM will use full copies, which is a lot of disk space (2).
I've also compiled libvirt-1.0.3rc3 and linked /usr/libexec/qemu-kvm -> /usr/local/bin/qemu-system-x86_64. Before I was getting error message about qemu-kvm not supporting vmdk. I'm not entirely sure I needed to build new libvirt, but I worked OK.
With the changes above I was able to load VMware VM (vmdk) on KVM host (CentOS Linux as guest, will try Win later).
(There are some bugs in CentOS6 and libvirt-1.0.2/1.0.3rc3 with SELinux enabled, so SELinux is disabled on the VM Hosts).
Q.:
1. Should qemu-img work with $image.vmdk files? The $image.vmdk file is description files for $image-flat.vmdk. If qemu-img is not suppose to 'follow' to $image-flat.vmdk file, then this could be adjusted in libvirt.pm code.
2. Is there a way to make a linked clone from .vmdk file (i.e. copy of write disk)? Can .vmdk file be converted to .qcow2 file as linked clone?
I would like to stay with CentOS6 as host OS if possible, but if #2 above works in Fedora and I cannot make it work in CentOS then I'll try Fedora 16 as host.
Thanks.

Re: Running VMware images on KVM host
Posted by Andy Kurth <ar...@ncsu.edu>.
The versions we are running are listed below. Older versions of qemu-img does
not convert correctly from 2gbsparse vmdk to qcow2. Check the actual size if
the qcow2 file that was created with du. It may be 0 or much smaller than the
original vmdk image. They should be similar in size.
You can download libvirt/KVM and install it. I have never done this. The
options are daunting. It would be helpful if someone could figure it out and
add instructions to the site.
I don't think VMware Tools is the problem but it's better to uninstall it
before converting an image to KVM if possible. Once the image is running on a
KVM vm you can't run setup to uninstall it completely. There are cleanup
tools but they don't get everything.
libguestfs 1.12.7
libguestfs-tools 1.12.7
libguestfs-tools-c 1.12.7
perl-Sys-Guestfs 1.12.7
libvirt 0.9.6
libvirt-client 0.9.6
libvirt-python 0.9.6

qemu-common 0.15.0
qemu-img 0.15.0
qemu-kvm 0.15.0

I'm compiling qemu-1.4.0 right now and will try it with the new version.
Thank you.

We got it working by compiling qemu-img from source.
If you want to try it, you can grab http://orec.rdc.uottawa.ca/qemu-img.
NOTE: This might NOT be the best solution, but it's been working good for us.

Hi
I'm trying to use CentOS 6.3 as KVM host.
qemu-img fails to convert .vmdk files. It's sees .vmdk as raw format and ignores actual data in -flat.vmdk file.
I assume this is b/c of older version of qemu-img?
qemu version in CentOS 6 is 0.12. Latest version on Qemu.org is 1.4.0.
What is the version of qemu package that comes with Fedora 16?

Re: Running VMware images on KVM host
Posted by Dmitri Chebotarov <dc...@gmu.edu>.
Hi
I'm trying to use CentOS 6.3 as KVM host.
qemu-img fails to convert .vmdk files. It's sees .vmdk as raw format and ignores actual data in -flat.vmdk file.
I assume this is b/c of older version of qemu-img?
qemu version in CentOS 6 is 0.12. Latest version on Qemu.org is 1.4.0.
What is the version of qemu package that comes with Fedora 16?
Thanks.

We are also running a mix of VMware and KVM host servers. We are using Fedora
16 as the KVM host. VCL can automatically deploy images captured on either
one to either host type. Andy might be able to speak better to any
requirements for it to work, but as long as you follow the online instructions

We have a mixed vmware/kvm setup.
I think one thing we were missing initially was "libguestfs-winsupport" package. Which caused issues with windows machines moving from vmware to kvm.
We run our vcl on CentOS 6.
Hope this helps.

Hello
Have anyone succeeded in running VMware/KVM mixed environment for VCL?
I'm having difficulties starting Windows 7 VMware images on KVM: the image would convert and load, but Windows gets blue screen.
I assume this is due missing virtio drivers while attempting to run Windows on KVM.
We also have VMware tools installed on Windows image, which may also contribute to the problem.

Thanks, that's a good point regarding IDE. Again I'm OpenStack biased as it
uses virtio by default to boot vms. :)

Re: Running VMware images on KVM host
Posted by Young h Oh <oh...@us.ibm.com>.
Dmitri,
How did you convert the Windows 7 VMware images? I've converted many VMware
images to KVM iamges using qemu-img command but there was no problem for
the Windows 7 images. (e.g., qemu-img convert VMware-Windows7-flat.vmdk -O
raw KVM-Windows7.img). I think the blue screen might be caused by the wrong
definitions in the VM's XML file, especially the disk format. Probably, you
need to set the disk bus type to "ide" instead of virtio. For more detail
setting, please refer to http://libvirt.org/formatdomain.html. Also, the
VMware tools in your converted KVM image can cause errors but not the blue
screen. I hope this would be helpful.
Thanks,

I am not an expert with Windows by any stretch, but yeah, your

When we migrated from ESXi to OpenStack + KVM I had to convert all our
