Thanks Avi, "ACPI Multiprocessor PC" was/is the default HAL, I didn't change anything when the system was originally installed. I'm curious why the RHEL 6 documentation claims that you actively need to select the "Standard PC" HAL on installation, if it's not even the recommended/preferred HAL...(?): "Windows 2003 requires a specific computer type in order to install properly on a fully-virtualized guest. This needs to be specified at the beginning of the installation process."[1] [1] http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/sect-Virtualization_Windows2003.html Best regards Kenni -- 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
