This is a deficiency in the grant table mechanism where it can't currently wait on live entries for their destruction. If upstream's plan to use copying instead of flipping gets extended to the domU=>dom0 direction this should no longer be an issue. change QA contact This report targets FC6, which is now end-of-life. Please re-test against Fedora 7 or later, and if the issue persists, open a new bug. Thanks |
