Hello,
I have a host machine (Dom0) running OpenSUSE xen kernel version 3.11.10-21.1.
I am using the xl tool stack to the extent I can.
I have installed freedos as a guest.
I am encountering errors such as
"Error reading from drive C: DOS area: write-protection violation attempted
(A)bort, (I)gnore, (R)etry, (F)ail?"
immediately after boot but a C prompt eventually comes up after a few "A"s.
I have an MSDos 6.22 vm which runs without complaint.
The xl configuration files are almost identical. Here is the freedos config
file:
code
name = "freedos_1.1_n01"
uuid = "11071171-4e33-4182-8ff7-e1d3bbe80928"
#
maxmem = 512
memory = 512
vcpus = 1
#
on_poweroff = "destroy"
on_reboot = "destroy"
on_crash = "destroy"
#
localtime = 0
keymap = "en-us"
builder = "hvm"
#device_model = "/usr/lib/xen/bin/qemu-system-i386"
#kernel = "/usr/lib/xen/boot/hvmloader"
boot = "cd"
disk = [ "file:/v/v.../freedos_1.1_n01-hda.raw,hda,w",
"file:/v/../freedos_1.1_src.iso,hdc:cdrom,r" ]
#
vif = [ "bridge=virbr0,ip=192..03,mac=00...e" ]
#
pae = 1
acpi = 1
apic = 1
#
#
vnc = 1
vncunused = 1
#
serial = "none"
parallel = "none"
soundhw = "sb16"
#
stdvga = 0
endcode
This is the type of error I would see on a damaged floppy drive or one with the
write protection slot covered, or on a failing/failed C drive; but freedos
installed on this image file without any trouble (after I got the order of
operations right).
If images are permitted, I can send a screen shot of the display.
Since
1) I am running as root (and therefore should not encounter any permissions
problems) and
2) MSDos runs without trouble and
3) freedos installed and is obviously running
I am assuming xen is OK and that my configuration file is OK, but could I have a
timing issue?
Is the CPU too fast? ( I-7 @ 2200GHz)I have seen some notes which mentioned
throttling back a cpu. I tried caping the CPU at 20% which did not seem to
help.
If someone has some idea as to the cause of and cure for this behavior, I would
like them to share it with me.
TKA
Bill
