[libvirt-users] Split a qcow2-image?
by Stefan G. Weichinger 26 Jul '11

26 Jul '11

Hello, I converted a W2003-Server to a vmdk-image, I didn't think too much back then ... Now I have 2 windows-drives C: and E: inside one vmdk-image-file, which was converted to qcow2. I have installed drivers and stuff into that VM already and would like to avoid to start over again with the vmdk-file -> Is there a way to split that one qcow2 into 2 separate files, one for each windows-harddisk? or plan B: can I possibly enlarge the part of C: inside that qcow2? I use qemu-kvm on gentoo linux, and libvirt-0.9.3-r1. I would appreciate any help on this topic! Thanks Stefan

[libvirt-users] problem w/ libvirt-0.8.2-15.el5 and CentOS
by Jim Glennon 20 Jul '11

20 Jul '11

I am running the Eucalyptus 2.0 cloud computing platform on an up-to-date CentOS 5 using the xen hypervisor. While attempting to attach a volume successfully created using jclouds with eucalyptus to a running VM instance, I encountered the following error: libvirt: Requested operation is not valid: Xm driver only supports modifying persistent config (code=55) i also tried attaching manually (i.e. euca-atttach-volume) and experienced the same failure. i found this discussion which mentions a possible libvirt/xen problem: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=662908 however it does not appear that the fix is available for public consumption (at least i couldn't find it). from the Eucalyptus nc.log: [Tue Jul 19 22:16:47 2011][005714][EUCAINFO ] doAttachVolume() invoked (id=i-4DA80924 vol=vol-59CF0630 remote=/dev/etherd/e0.12 local=/dev/sda2) [Tue Jul 19 22:16:48 2011][005714][EUCAERROR ] libvirt: Requested operation is not valid: Xm driver only supports modifying persistent config (code=55) [Tue Jul 19 22:16:48 2011][005714][EUCAERROR ] AttachVolume() failed (err=-1) XML= [Tue Jul 19 22:16:48 2011][005714][EUCAERROR ] ERROR: doAttachVolume() failed error=1

Hi,  I was finally able to connect to the xenapi hypervisor using virsh of libvirt 0.9.2.  However, once I connect to virsh and give a 'quit' command I get  "* glibc detected *** virsh: double free or corruption (fasttop):". Please find below the actual memory dump.   Note: I have disabled the SSL certificate verification in xenapi_driver.c by setting curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0) &
