Hello,
I'm testing the new Fedora7 under KVM. As you may know Fedora has
migrated to the new libata drivers.
ata_piix is unhappy with the PIIX IDE controller provided by QEmu/KVM:
libata version 2.20 loaded.
ata_piix :00:01.1: version 2.10ac1
PCI: Setting latency timer of device :00:01.1

Guests use this number as a hint for alignment and I/O request sizes.
It's not just a hint. It is also the radius of corruption on failed
write - important for journalling filesystems and databases.

Dynamic ticks in Qemu: have a SIGALRM generated only when it is
needed, instead of every 1 millisecond. This patch requires that the
host supports high resolution timers, since it arms a POSIX timer to the
nearest Qemu
Allow user to override the list of available alarm timers and their
priority. The format of the options is -clock clk1,clk2,...

Hello,
in reply to this mail I will send a serie of 4 patches that cleans up and
expands
the alarm timer handling in QEMU. Patches apply to current kvm-userspace tree,
but I think I can rebase it to QEMU svn if desired.
Patch 1 is mostly a cleanup of the existing code; instead of having multiple
Make the alarm code modular, removing #ifdef from the generic code and
abstract a common interface for all the timer. The result is functionally
equivalent to the old code.

No surprises here, you can see the additional 1k syscalls per second.
This is very surprising to me. The 6.2% difference
