scsi broken > 4GB RAM

scsi broken > 4GB RAM

[Henrik Holst]

I do not know if this is a bug in qemu or the linux kernel sym53c8xx
module (I haven't had the opportunity to test with anything other than
Linux at the moment) but if one starts an qemu instance with -m 4096
and larger the scsi emulated disk fails in the Linux guest.

If booting any install cd the /dev/sda is seen as only 512B in size
and if booting an ubuntu 8.04-amd64 with the secondary drive as scsi
it is seen with the correct size but one cannot read not write the
partition table.

Is there anyone out there that could test say a Windows image on scsi
with 4GB or more of RAM and see if it works or not? If so it could be
the linux driver that is faulty.

Hi,

I tried windows server 2008 (64 bit) on Proxmox VE 0.9beta2 (KVM 71), see http://pve.proxmox.com):

Some details:
--memory 6144 --cdrom en_windows_server_2008_datacenter_enterprise_standard_x64_dvd_X14-26714.iso --name win2008-6gb-scsi --smp 1 --bootdisk scsi0 --scsi0 80

The installer shows 80 GB harddisk but freezes after clicking next for a minute then:

"Windows could not creat a partition on disk 0. The error occurred while preparing the computer´s system volume. Error code: 0x8004245F."

I also got installer problems if I just use scsi as boot disk (no high memory) on several windows versions, including win2003 and xp. So I decided to use IDE, works without any issue on windows.

But: I reduced the memory to 2048 and the installer continues to work!

Best Regards,

Martin Maurer

Sorry, just returned to the installer - also stopped with the same error code, using just 2 gb ram.

RE: scsi broken > 4GB RAM

[Martin Maurer]

Using IDE boot disk, no problem. Win2008 (64bit) works without any problems - 6 gb ram in the guest.

After successful booting IDE, I added a second disk using SCSI: windows see the disk but cannot initialize the disk.

So SCSI looks quite unusable if you run windows guest (win2003 sp2 also stops during install), or should we load any SCSI driver during setup? Win2008 uses LSI Logic 8953U PCI SCSI Adapter, 53C895A Device (LSI Logic Driver 4.16.6.0, signed)

Any other expierences running SCSI on windows?

Martin

I've just tried with OpenBSD 4.3 and even with -m 256 it failed
miserable with the scsi driver. qemu wrote a million lines of:
"lsi_scsi: error: Reselect with pending DMA" to the console.

The same problem occured with -no-kvm so this seams to be a qemu
related problem. Has scsi always been this broken? Since IDE can only
handle a total of 4 drives and virtio is only available to linux
guests this makes KVM somewhat useless at the moment, arghh.
