Hi folks, I was doing some work at one of our host machines, the one that runs upstream (Fedora 14, kvm.git as the kernel and qemu-kvm.git as userspace), and I noticed the kernel message: kvm: unreliable cycle conversion on adjustable rate TSC kvm: SMP vm created on host with unstable TSC: guest TSC will not be reliable The host being tested in this case was RHEL 5.5 i386. Command line of the install test: /usr/local/autotest/tests/kvm/qemu -name 'vm1' -monitor unix:'/tmp/monitor-humanmonitor1-20101021-160403-PrKT',server,nowait -qmp unix:'/tmp/monitor-qmpmonitor1-20101021-160403-PrKT',server,nowait -serial unix:'/tmp/serial-20101021-160403-PrKT',server,nowait -drive file='/tmp/kvm_autotest_root/images/rhel5-32.qcow2',index=0,if=ide,cache=none -device rtl8139,mac=9a:47:46:1a:e6:b9,netdev=idAcPzhW -netdev user,id=idAcPzhW,tftp='/usr/local/autotest/tests/kvm/images/rhel55-32/tftpboot',bootfile='/pxelinux.0',hostfwd=tcp::5000-:22,hostfwd=tcp::5001-:12323 -m 1024 -smp 2 -drive file='/tmp/kvm_autotest_root/isos/linux/RHEL-5.5-i386-DVD.iso',media=cdrom,index=2 -drive file='/tmp/kvm_autotest_root/images/rhel55-32/ks.iso',media=cdrom,index=1 -vnc :0 -boot d -boot cn I was oriented by Marcelo to report this to the kvm list and copy Zach on the e-mail. There, done :) Lucas -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
