I did tried my full IP address and obtained the same result. I googled a bit and found that the problem may be caused by improperly configured ramdisk.

I'm not sure how your DNS server is configured, but it must somehow be returning a non-127.0.0.1 IP address for "localhost". I agree that iPXE must be connecting to an iSCSI target, since it's definitely loading something, and since I think you have only one iSCSI target then it must indeed be connecting to the correct iSCSI target. However, it might be a good idea to change "iscsi:localhost:..." to something saner, e.g. "iscsi:192.168.1.4:..." (or whatever the IP address or DNS name of the target really is). That aside, with regard to the problem you are seeing: > Virtualbox appears to have found and loaded the iSCSI target, but after a > few seconds virtualbox shows: "Unable to locate IOAPIC." (see attached > screenshot for more detail). Then, virtualbox shows: "No root device > found" and "Boot has failed, sleeping forever." It sounds as though you are successfully loading the Fedora kernel from the iSCSI target. The "Unable to locate IOAPIC" messages are coming from the loaded kernel, and seem to be harmless according to this thread: http://www.fedoraforum.org/forum/showthread.php?t=256241 The problem seems to be that Fedora has either failed to connect to the iSCSI target, or connected to the target but failed to mount the root partition. iPXE has done its part; there's no more iPXE debugging to be done. You probably need to see some more verbose boot messages from Fedora to help figure out the problem. Assuming you're using grub, try removing the word "quiet" from the kernel command line before allowing it to boot. Michael
