Thanks, I will try that. Yanik
From: Andy Kurth [mailto:[email protected]] Sent: Monday, November 12, 2012 9:35 AM To: [email protected] Subject: Re: libvirt qemu-img As Aaron mentioned, we are running Fedora 16 because of the problems converting images. You need one of the latest versions of qemu-img in order for it to be able to convert multi-file vmdk's. When the module was being developed last spring, the version included in CentOS and RHEL failed to properly convert the images. Fedora 16 does include a working version. Since compiling libvirt/KVM can be quite a chore, we just run Fedora 16. Regarding the VMs not being deleted, I think you encountered this issue: https://issues.apache.org/jira/browse/VCL-641 The underlying problem resides in get_domain_info. Please try making the change explained in the Jira issue and reverting the change you made to delete_existing_domains. This will be fixed in 2.3.1. -Andy On Mon, Nov 12, 2012 at 8:53 AM, Yannick Charbonneau <[email protected]<mailto:[email protected]>> wrote: Thanks, I ran into another issue; vms were NOT being destroyed before new ones were reloaded, causing vms to pileup on the host. If found problems on our setup in libvirt.pm<http://libvirt.pm>; Issue #1; The statement "next if ($domain_name !~ /^$computer_name:/);" in sub delete_existing_domains didn't work for me. I had to replace it with "if ($domain_name =~ $computer_name) {" ..."}" (this might have risks involved, if the image has $domain_name in it name). Issue #2 Then I had to ADD a bunch of "$domain_name =~ s/^\s+|\s+$//g;" where virsh was being called. This was required because $domain_name had leading spaces which would make virsh fail. Again, I think most of those issues are caused by us using older version of libvirt and qemu/KVM. Existing vms are now destroyed before loading new ones in their slot.
