I add this line in my xml definition for libvirt : <timer name='hpet' present='no'/> in the clock block. And I see the -no-hpet in the command line : /usr/bin/kvm -S -M pc-1.0 -enable-kvm -m 16384 -smp 2,sockets=2,cores=1,threads=1 -name rds1 -uuid 4f72a64e-de1a-b3da-adac-5dffdb9eb6aa -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/rds1.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime -no-hpet -no-shutdown -drive file=/dev/drbd1,if=none,id=drive-virtio-disk0,format=raw,cache=none,aio=native -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/Iso/SW_DVD5_Windows_Svr_DC_EE_SE_Web_2008R2_64-bit_French_X15-59758.ISO,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=18,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:16:36:0c:a1:c4,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -device usb-tablet,id=input0 -vnc 127.0.0.1:0 -k fr -vga std -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 But unfortunatly, the result is the same : always 12s to runs this function (to remember 8s on ESXi 4).
