+virtfs: kernel compile fails
+
+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 nic,model=virtio,macaddr=DE:AD:BE:EF:AA:BB -net tap,ifname=qtap0,script=no

+Hi Avishay,
+
+Are you running qemu as a normal user? In that case, could you please check whether normal user has rw access to the kernel source?
+
+Also could you please attach the output of strace scripts/kconfig/conf --silentoldconfig Kconfig ?
+
+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!
+
+Triaging old bug tickets ... can you still reproduce this problem with the latest version of QEMU?
