I've been trying to get VMware working with a plain scsi disk without
much luck. I'm running into problems fairly late when I'm trying to
get WNT (have tried W2K too) installed. The guest sees the plain disk
and after it formats the partition I've given it, it claims the disk
is corrupt & tells me to choose another.
Can anybody offer any suggestions as to what I'm doing wrong?
I'm running the latest vmware2 under 4.0-RELEASE.
% grep da1 /var/run/dmesg.boot
da1: 8683MB (17783240 512 byte sectors: 255H 63S/T 1106C)
% cat ~/.vmware/plain
DRIVETYPE scsi
CYLINDERS 1106
HEADS 255
SECTORS 63
ACCESS "/home/home1/gallatin/.vmware/disk.mbr" 0 63
ACCESS "/dev/rda1s1" 63 17767827
#RDONLY "/dev/null" 4192965 12305790
And the disks my vmware knows about:
scsi0:0.present = TRUE
scsi0:0.deviceType = "plainDisk"
scsi0:0.fileName = "/home/home1/gallatin/.vmware/plain"
scsi0.present = TRUE
ide0:0.present = TRUE
ide0:0.deviceType = "atapi-cdrom"
ide0:0.fileName = "/dev/rcd0c"
The disk in question looks like this:
#fdisk /dev/rda1
******* Working on device /dev/rda1 *******
parameters extracted from in-core disklabel are:
cylinders=1106 heads=255 sectors/track=63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=1106 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 63, size 17767827 (8675 Meg), flag 80 (active)
beg: cyl 0/ sector 1/ head 1;
end: cyl 1023/ sector 63/ head 254
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
Oddly enough, if I give it the slice, I see partitions:
# fdisk /dev/rda1s1
******* Working on device /dev/rda1s1 *******

end: cyl 0/ sector 0/ head 0
I'm trying to save memory by avoiding double caching of data in the
guest and the host & I'd like to avoid going back to using a file..
Thanks,
Drew
