Description (last modified by )
My host is HP ProLiant ML370 G5 E5410 Intel Xeon 2.33GHz/12M 1333, 4 GB HP SA P400/256 RAID SAS, BBWC, DVD-RW 10/100/1000 lan 6x HP HDD 72GB, SAS-I 15K, 2.5' hot plug
I use binaries for SLES 10, 64bit - http://download.virtualbox.org/virtualbox/4.1.6/VirtualBox-4.1-4.1.6_74727_sles10.1-1.x86_64.rpm
Host OS is SLES 10, SP1 and I want to install single guest OS, preferrably windows 7 64bit, for that, I need VT-x enabled, so: 1, I've upgraded BIOS to latest version (2011.05.02, 20 Jul 2011) and enabled "No-Execute Memory Protection" and "Intel® Virtualization Technology" options in BIOS. 2, I did cold restart (plugged out power cord before) 3, I've installed Virtualbox (specific build for SLES10, 64bit) 4, When I enable IO-ACPI option in VM's settings, whole machine will freeze shortly after start, sometimes 5seconds, sometimes 2minutes. It doesn't matter if VT-x is enabled or not, nor if I've assigned 1 or 3 CPU's to the VM, nor the amount of memory, nor if the VM is 32bit or 64bit. It seems like I've tried all the combination, but it all goes down to "IO-ACPI" feature. I enable it, machine freezes (not only gdm, the whole machine, I can't even switch to command line)
I want to use 64bit guest and be able to assign more than 1 cpu core to the VM and without IO-ACPI it's not possible, so I'm stuck here.
I've attached log from my last attempt to start installation of win7, 64b, but from what I see, freeze is random and there is nothing obvious in virtualbox log. I also browsed the linux system logs, but found nothing helpful. System just hangs and needs cold restart.
