Hello, I am unable to do a graceful shutdown or reboot of SLES 10 SP4 virtual machines (Kernel version: 2.6.16.60-0.85.1-default) with virsh shutdown or virsh reboot commands. (e.g virsh shutdown "vmname" ). On issuing these commands there is no impact on the VM. Also unable to perform the shutdown or reboot operations from the menu options available on the console when accessing the VM via the virt-manager. The virsh shutdown/reboot commands and the shutdown/reboot menu operations work fine for SLES 11 SP2 VMs. I've verified that the acpi daemon is running with the SLES 10 SP4 VM linux-kb8x:~ # ps aux | grep acpi root 8 0.0 0.0 0 0 ? S< 16:27 0:00 [kacpid] root 9 0.0 0.0 0 0 ? S< 16:27 0:00 [kacpi_notify] root 1830 0.0 0.0 2688 528 ? Ss 16:27 0:00 /sbin/acpid Is there any other process that needs to running for these operations to work or is there a known issue with SLES 10 SP4? Thanks, Padmaja
