 Hi all,

first of all I'm a bit confused:

What is the difference between qemu with command line option --enable-kvm
and qemu-kvm?
It seems to be a difference in code so far, from the performance point of
view it seems to be the same...

Now my issue that lead me to a git bisect on qemu-kvm:
The following commit / merge breaks my windows guest boot sequence and
causes resets infinitely:
ec757c67c40a56492001487e69272f62144fd124 Merge branch 'upstream-merge' into
next

Interesting: qemu with --enable-kvm master and the same command line
options as qemu-kvm runs perfect.
My command line options are:
qemu-system-x86_64 -serial /dev/ttyS2 -readconfig /etc/ich9-ehci-uhci.cfg
-device usb-host,bus=ehci.0 -device usb-tablet -drive
file=/dev/sda2,cache=off -m 1024 -net nic,macaddr=$MACADDR -net
tap,script=/etc/qemu-ifup -no-acpi -monitor stdio -L /usr/X11R6/share/qemu
-boot c -localtime


Best regards,

Erik
