But it still have some stop time (about 8~10s) after loading the Grub for a RHEL6.x guest. I found even an old CS #23124 (about 1 year ago) also has the same phenomenon. Currently, RHEL6.2 or RHEL6.3 guest can bootup in 30~40s (for either RAW or QCOW2 image). And, RHEL5.5 guest (which has no stop time issue) can bootup in 50~60s. I also commented in the bugzilla. You can also have a look for more details. Will you want still track or fix this old issue ? If not, I want to marked it as "fixed and verified".
