Fixed In Version: xen-3.0.3-94.el5_4.5
Doc Type: Bug Fix
Doc Text:
Previously, creating a new domain caused a hot plug script to perform an additional check of disk sharing capabilities. With a large number of virtual block devices (VBDs), this operation could take a long time, and an attempt to create a new domain could fail due to a timeout. Since a similar checking mechanism is already implemented in the xend service, this update removes this algorithm from the hot plug script, so that it no longer causes a domain creation to fail.
