Hi,
i compile qemu on my own.
I have the rom files under /usr/share/kvm and they look like this:
ls -la /usr/share/kvm/*.rom
-rw-r--r-- 1 root root 173568 May 14 09:39 /usr/share/kvm/efi-e1000.rom
-rw-r--r-- 1 root root 174592 May 14 09:39 /usr/share/kvm/efi-eepro100.rom
-rw-r--r-- 1 root root 173056 May 14 09:39 /usr/share/kvm/efi-ne2k_pci.rom
-rw-r--r-- 1 root root 173056 May 14 09:39 /usr/share/kvm/efi-pcnet.rom
-rw-r--r-- 1 root root 176640 May 14 09:39 /usr/share/kvm/efi-rtl8139.rom
-rw-r--r-- 1 root root 171008 May 14 09:39 /usr/share/kvm/efi-virtio.rom
-rw-r--r-- 1 root root 67072 May 14 09:39 /usr/share/kvm/pxe-e1000.rom
-rw-r--r-- 1 root root 61440 May 14 09:39 /usr/share/kvm/pxe-eepro100.rom
-rw-r--r-- 1 root root 61440 May 14 09:39 /usr/share/kvm/pxe-ne2k_pci.rom
-rw-r--r-- 1 root root 61440 May 14 09:39 /usr/share/kvm/pxe-pcnet.rom
-rw-r--r-- 1 root root 61440 May 14 09:39 /usr/share/kvm/pxe-rtl8139.rom
-rw-r--r-- 1 root root 60416 May 14 09:39 /usr/share/kvm/pxe-virtio.rom
currently i don't know what's wrong.
