[Fedora-xen] Libvirt and xenstore - glitches on migrate

[Jim Klein]

Nothing major, but when migrating with the current Red Hat xen bits and libvirt on F8 and RHEL, libvirt and virt-manager have all sorts of trouble (though the migrate works fine.) Example below is two laptops, the first with and NFS share of /var/lib/xen/images and the second attached to that share. On a migrate, source console kicks out out of memory errors on xenstore, and virt-manager status for the machine being migrated oscillates between "Running" and "Shutoff." No errors on the target machine. Console errors are listed below: 

xm migrate -l rhel4 turion64 
libvir: error : invalid argument in __virGetDomain 
libvir: Xen Store error : out of memory 
libvir: error : invalid argument in __virGetDomain 
libvir: Xen Store error : out of memory 
libvir: error : invalid argument in __virGetDomain 
libvir: Xen Store error : out of memory 
libvir: error : invalid argument in __virGetDomain 
libvir: Xen Store error : out of memory 
libvir: error : invalid argument in __virGetDomain 
libvir: Xen Store error : out of memory 
libvir: Xen Daemon error : internal error domain information incomplete, missing name 

Nothing abnormal in xend.log or xend-debug.log, and the migrate works fine, just general ugliness in the interface (which is a bummer if you are doing a demo in front of an audience.)
