After a great struggle I got my XEN installed now I am using virt-manager and trying to create a VM. Since my H/W doesnt support full Virtualization using the Para Virtualization installation over network. After I specify all the details like URL , N/w etc., I get the following error:
Unable to complete install: 'POST operation failed: xend_post: error from xen daemon:
(xend.err "Error creating domain: 'NoneType' object has no attribute 'rfind'")
The complete error:
Unable to complete install: 'POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: 'NoneType' object has no attribute 'rfind'")'
DETAILS->
Unable to complete install '<class 'libvirt.libvirtError'> POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: 'NoneType' object has no attribute 'rfind'")
