I've been trying see if I can use a vmlinux kernel binary image with kvm tool.
If use a bzImage as
lkvm run -k .../bzImage --console serial -d /dev/null
which runs until it expectedly dies since I didn't give it an initramfs or disk.
However, when I try:
lkvm run -k .../bzImage --consol
On an x86 32bit system (and using the 32bit CodeSourcery toolchain on a x86_64
system) I get:
evensky@machine:~/.../linux-kvm/tools/kvm$ make
CC util/util.o

There was a patch (quoted below) that changed networking at the end of
September. When I
try to set the guest_mac from the usage in the patch and an admittaly too
brief a look at the code, the guest's mac address isn't being set. I'm using:
sudo /path/to/linux-kvm/tools/kvm/kvm run -c 1 -m 256
for debugging guest kernel using KGDB:

Hi. Is it possible to use kvm-tool with a kernel compiled with kgdb?
I've tried adding 'kgdbwait kgdboc=ttyS0' to -p, but that doesn't seem
to work.

No, the code needs a physical
Sasha,
That is wonderful. It sounds like it should be OK, and will be happy
to test.

Adding in the rest of what ivshmem does shouldn't affect our use, *I
think*. I hadn't intended this to do everything that ivshmem does,
but I can see how that would be useful. It would be cool if it could
grow into that.
Our requirements for the driver in kvm tool are that another program

Sasha,
I've done a pull to get patch below and otherwise sync up and got an
ioremap error. It is a little different from the patch I got from you
previously that worked. The patch that worked changed pci.c as:
- u8 bar = offset - PCI_BAR_OFFSET(0);
+ u
I don't know if there were any other drivers for this patch, but it
along with another patch (maybe integrated elsewhere for 32bit BAR vs
8bit) certainly helped me out a lot. These patches fixed ioremap
errors I was seeing (I had a 16MB PCI memory region, but it appeared
to be only 256 bytes in s
Is that a pointer to the coding standards used for the kvm tools?
Thanks,
\dae
