Ticket #6976 (closed defect: invalid)
64-bit Windows 7 guest refuses to finish installation on 64-bit Lucid host
|Reported by:||xtknight||Owned by:|
I've got an Ubuntu Lucid 64-bit host and also a CPU with vmx support (Core i7). Motherboard is ASUS P6T Deluxe. kvm modules are not loaded on Ubuntu, and should not interfere with VMX.
I ran memtest86+ inside of the VM and there were no errors reported. I am almost certain this is either a VT-x issue or hard drive controller problem.
All the errors I get could have been caused by the VT-x feature or the hard drive controller. One time I got KERNEL_STACK_INPAGE_ERROR and other times I just get messages saying a file is corrupt and the Windows installation has to stop.
I have tried with and without nested paging, PAE/NX, 1 cpus, 2 cpus, video memory adjustments, 2d/3d acceleration, Host I/O caching on the cd (booting from an ISO) and hard drive, on an ext4 mdRAID5 and xfs non-raid partition. A SCSI controller. A PIIX4. An ICH6. Nothing fixes it. I obviously haven't tried all permutations of those, but I've tried a lot of things. I tried increasing the RAM from 1024MB to 1536, doesn't fix it. There is nothing in any log that I've seen. The bug is deep down in there somewhere.
Why would this be a 64-bit issue? My Windows 7 32-bit guest doesn't have a single error.
I've run Windows 7 64-bit guests under VIrtualBox before with no issues (on older Ubuntu hosts, on "Sun VirtualBox" before the Oracle switchover). I did update my BIOS since then, but honestly, I doubt it's this, anyway. My motherboard has been rock solid and every problem I've ever had was a software one.
Each time I'm allocating a 40 GB disk dynamically on either ext4(thru MDRAID) or xfs. I then tried allocating a 20 GB fixed disk on my xfs partition, and that also failed.
I did not try the patch posted here because I statically allocated my disk and it still happened.
Every time I am reading an ISO from disk. I am going to try and burn the ISO and use my actual CD drive.
If you want any sort of background on any component in my computer, let me know, but I posted what I felt was pertinent here.
