Seems like low priority to me (correct me if I'm wrong). Postpone to next release
moving to component etherboot, which is the guilty one in here. However, It will probably never have a fix in etherboot, because etherboot community reaction seems to be "etherboot is deprecated, use gpxe instead". So what we shoul really focus on, is in having gpxe working with this test case, and fix it otherwise.
this problem still exists when using gpxe. cmd: /usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -smp 1 -m 1024 -cpu qemu64,+sse2 -uuid 998CE821-499E-11CB-8FF3-8F2C8D363AF0 -net nic,model=rtl8139,macaddr=00:23:19:21:2B:9F,vlan=0 -net tap,vlan=0,script=/etc/qemu-ifup -drive file=xx.img,if=ide -fda gpxe.dsk -boot a -vnc :2&
(In reply to comment #3) > moving to component etherboot, which is the guilty one in here. Glauber, why do you think it's etherboot? It does not work from gPxe either and the bios code should run the ide.
I had debugged a similar problem in the past, and came to the conclusion that it happened because etherboot rewrote int19 handler, but then did not restore it when we gave up booting from network. It would mean that booting from local is then impossible. Note that it might be possible that gpxe has the same problem. The main advantage of gpxe is that it is not deprecated, and we can fix it.
