Hi,
I am running qemu as root.
The output from strace for the command that you requested shows that this is
the problem:
rename(".tmpconfig.h", "include/generated/autoconf.h") = -1 ENOENT (No such
file or directory)
The command fails because the directory 'include/generated' doesn't
exist because I ran only the command you mentioned, and not 'make'.
So I attached the output for: strace -f make &> /tmp/strace.out
Hope that helps, and thanks!

Title:
virtfs: kernel compile fails
Status in QEMU:
New
Bug description:
I am trying to compile a kernel under virtfs, and am getting an error.
The error does not occur when compiling outside of the virtfs mount.
Both guest and host are running the 3.0.4 kernel.
QEMU is latest from git: bc75c9e50d308b2ec6623a40179c5cdc84b63dae
QEMU command line:
/usr/local/bin/qemu-system-x86_64 -nographic -boot c -m 1024 -machine
type=pc,accel=kvm -drive file=/root/hdd1.img,if=virtio -drive
file=/root/test1.img,if=virtio -drive file=/root/test2.img,if=virtio -virtfs
local,path=/mnt/virtfs,security_model=none,mount_tag=virtfs -net
