Public bug reported:
Hi,
well, I'm in a similar boat as the one in #992067. But regardless any
memory-settings.
It takes "ages" in a cold-boot Windows 2008R2 with qemu-1.0.1, qemu-1.0.50 and
latest-n-greatest from today ( 1.0.50 /qemu-1b3e76e ). It eats up 400%
host-cpu-load until login-prompt is shown on the console.
Meanwhile I tried couple of settings with "-cpu features (hv_spinlocks),
hv_relaxed and hv_vapic. ".
Due to some Clock-glitches I start qemu-system-x86_64 with "-no-hpet".
With 2 processors the system is up after 2 minutes, with 4 procs almost
10 minutes... After a reset ( warmstart) the 4 proc-system is up after a
couple of 20 secs.
Hints welcome, though once started, the system seems to operate
"normally".
Thnx in@vance,
Oliver.
