Russell, Were you able to see that the storage pool actually knows about your volume, using "virsh vol-list <pool name>" You can also run "virsh vol-info <path to qcow2 file>" to check the size.

Subject: Re: [xcat-user] xCAT and KVM and dir:/// storage pools Yes, we did use 'vmstorage=dir:///' a lot. It works well. @Mark, could you help on this?

I ran “mkvm kvm1 -s 20G” which created the kvm1.hda.qcow2 file in /install/vms However, the KVM/QEMU system doesn’t see the storage properly. When Anaconda runs, it sees the virtual disk as very small, and not as 20G. On the other hand, if I set up an NFS exported storage pool, such as “chdef kvm1 vmstorage=nfs://<server-IP>/vms” and otherwise do the same commands, it works fine. Anaconda will run and it sees the virtual disk as 20G. I looked at /opt/xcat/lib/perl/xCAT_plugin/kvm.pm and it seems that it handles “dir:///” differently than “nfs://”, specifically in “build_pool_xml”. Does anyone use local storage pool via “dir:///” ? Is that a non-typical usage? this is xcat version 2.12.2 Thanks, Russ ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ xCAT-user mailing list xCA...@li... https://lists.sourceforge.net/lists/listinfo/xcat-user ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ xCAT-user mailing list xCA...@li... https://lists.sourceforge.net/lists/listinfo/xcat-user |
