I assume this is the correct list for QEMU?
I made a Scientific Linux (~RH-EL 4) QEMU guest, which works well, but
the time runs about a factor of two fast. Connecting to timeservers
somehow doesn''t help.
Does anyone know how I can address this?
Thank you,
Bill

In Xen paravirt DomU''s the time is indeed synced to Dom0. For fullvirt, or native QEMU guests, the Dom0 time has no bearing to the the guest''s time. So you need to run NTPD inside the guest VM for Xen fullvirt, or QEMU Regards, Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

It jumps to the correct time, then says: SYNCHRONISED to LOCAL(0) stratum 10 after which it seems to head off at double speed again...
