libvirt/KVM
Hi
Has anyone tried Libvirt in 2.3 RC3?
I've updated VCL 2.2.1 to VCL 2.3 and cannot get Libvirt working.
I've made some adjustments and able to successfully capture an image, but cannot make reservation based on the image.
I'm using CentOS 6.2 with KVM as VM host (yum groupinstall Virtualization 'Virtualization Client' 'Virtualization Platform' 'Virtualization Tools').
If Libvirt is working for you, could you please share your configuration (ie. VM host version and packages, VCL computer configuration, etc) ?

Re: libvirt/KVM
Posted by Andy Kurth <an...@ncsu.edu>.
I don't have a libvirtlinux OS entry. I use vmwarelinux for KVM-based
Linux images. This is what should be set when you capture a base
image using vcld --setup. There is no difference among OS modules
which point to the same Perl package path. The OS table is actually
somewhat of a mess right now. Eventually it will be
collapsed/normalized down so the is a single entry for all Linux
images, otherwise we will end up with n-squared entries (OS's and
provisioning types). Issue VCL-566 addresses this.

Re: libvirt/KVM
Posted by Dmitri Chebotarov <dc...@gmu.edu>.
Andy
I've tested initial image capture (vcld --setup) and made few changes.
With the changes everything works well. I can capture image, make reservation and update image.
There are still few warning in vcld.log during vcld --setup, but looks like those could be ignored.
I've attached PDF file with changes.
I'm not sure if these are really necessary, but I couldn't get it work without.
Please let me know if it makes sense...

Re: libvirt/KVM
Posted by Dmitri Chebotarov <dc...@gmu.edu>.
Andy
Success! Thank you for your help.
Correct, I'm working with KVM-based Linux image.
I was able to make it work with a slight changes.
Do you have any entries in vcl.OS table with installtype='libvirt'?
The only way I'm able to make reservations is by adding new entry into vcl.OS table and then setting image.osid to the id of the new entry (49 in my case):
This is the entry I've added:
select * from OS where installtype='libvirt';
+----+--------------+----------------------+-------+-------------+---------------+----------+
| id | name | prettyname | type | installtype | sourcepath | moduleid |
+----+--------------+----------------------+-------+-------------+---------------+----------+
| 49 | libvirtlinux | CentOS 5/6 (libvirt) | linux | libvirt | vmware_images | 5 |
+----+--------------+----------------------+-------+-------------+---------------+----------+
Thanks.

Re: libvirt/KVM
Posted by Andy Kurth <an...@ncsu.edu>.
I'm confused about what you're trying to load. Is
centos5image-kvmlinuxv4105-v0 a bare metal image? The reservation
info you sent earlier had this image being loaded on the virtual
machine sandbox-vcl-19.
Assuming you have a Linux VM image, its OSid should be set to
vmwarelinux, which should be pointing to VCL::Module::OS::Linux.
The computer.provisioningid value of the VM should be set the libvirt
entry in the provisioning table, which should be pointing to
VCL::Module::Provisioning::libvirt.

Re: libvirt/KVM
Posted by Dmitri Chebotarov <dc...@gmu.edu>.
I think I'm missing something here. I fail to understand how KVM-based image is linked to libvirt.pm/KVM.pm modules in this case (and if it should).
Once I set image.osid to 36, (36 is os.id for vmwarelinux, module 5 - VCL::Module::OS::Linux), vcld is trying to load KVM-based image to a computer with Provisioning Engine set to VMware and using a VMware host. It fails.
In this case (image.OSid = 36) there is no link between KVM image and libvirt computers/KVM hosts.
Thanks.

Re: libvirt/KVM
Posted by Andy Kurth <an...@ncsu.edu>.
image.OSid should be set to the id that corresponds to vmwarelinux.
OS.moduleid should point to the os_linux module table entry, which has
module.perlpackagepath = VCL::Module::OS::Linux.

Re: libvirt/KVM
Posted by Dmitri Chebotarov <dc...@gmu.edu>.
Andy
It's pointing to VCL::Module::Provisioning::libvirt
This is a result of my earlier attempt to troubleshoot the issue. I've added new OSid, moduleid.
The original image.osid was 29, which is CentOS Bare Metal, processed by VCL::Module::OS::Linux.
With image.osid set to 29 VCL was trying to use xCAT module to process KVM reservations.
At this moment I don't have any xCAT (bare metal) computers available and once I select the [KVM] image for reservation I get popup asking to select available time for reservation, which means that I don't have available resources to support this reservation.
When I've added new OSid and moduleid (pointing to VCL::Module::Provisioning::libvirt), I'm able to start reservation, VCLd finds available computers (which are configured to use libvirt engine) and attempts to make reservation on correct KVM host, but fails with error attached in previous email.
What should image.osid, moduleid be set to?

For some reason the OS module for the image being loaded is showing as
VCL::Module::Provisioning::libvirt. Check which module
centos5image-kvmlinuxv4105-v0 is configured to use in the database:
image.OSid --> OS.moduleid --> module.perlpackagepath

Andy
I did 'svn up' and ran install_perl_libs.pl as well.
While trying to make reservation still getting an error. Attached is reservation log.
I'll try to trace the error, if you see something what causes it, please let me know.
I'll try to capture image with new code little later today and will let you know if it fails.
Thanks.

Re: libvirt/KVM
Posted by Andy Kurth <an...@ncsu.edu>.
There were some definite bugs which I hopefully corrected with the
commit from this morning. Be sure to use the latest code from trunk.
Also, you'll need to run install_perl_libs.pl again.
Regarding KVM installation/configuration, I have mainly been working
off of Fedora 16. The version of KVM included with Fedora 16 seems
more stable than Red Hat or CentOS 6.x. The code should work under
these OS's but automatic conversion of existing ESXi images to
KVM-compatible qcow2 images probably won't work. The version of
qemu-img included with Fedora 16 is able to do the conversion
correctly. The versions included with Red Had and CentOS do not.
Regarding image conversion, you should be able load an existing vmdk
ESXi image on KVM if the image resides in the repository path. The
code should copy it to the datastore in the format specified for the
image type in the VM profile for your KVM host. Be sure to set this
to qcow2.
I fixed some bugs which caused base image creation to fail in the
commit this morning. Please try this out.
I started the following page which describes which components to
install and how to configure networking and storage:
