This bug has been addressed in linux-next. Please refer to:I am able to boot the kvm guest after applying the following two patches.
f06dd16a03f6f7f72fab4db03be36e28c28c6fd6 : IMA: Handle dentry_open failures
1a62e958fa4aaeeb752311b4f5e16b2a86737b23 : IMA: open all files O_LARGEFILE
04288f42033607099cebf5ca15ce8dcec3a9688b : integrity: ima audit dentry_open failure
The default policy in 2.6.30 measures all files open for read by root.
(So starting the VM as root will cause it to be read.) This linux-next
patch changes the default behavior so that nothing is measured.
