Comment 9 for bug 1174654

I don't know if this will help, but I had a similar problem.

When creating a snapshot image of an XP machine, all works just fine when loading it. As time passes on the host the loadvm start to become very slow.

To reproduce:
1. Create a snapshot image (savevm)
2. leave QEMU
3. move the *HOST* clock one month in the future
4. Start QEMU with -loadvm

It turns out that the "-rtc clock=vm" made this disappear. When using the default caused the problem.
