It is like it forgets to boot the kernel and initrd again after a reboot and tries to boot from the harddrive instead. More weirdness with direct booting - using more than 2048MB causes the BIOS to repeatedly crash out. This only happens using -kernel and -initrd.

Direct kernel booting is supported. Please try with -no-kvm to see if it is a qemu or kvm issue, and also try the latest release to see you aren't encountering an already-fixed bug.

Direct kernel boot without harddrive image
Hi, Admittedly this looks more like a Qemu issue but it effects KVM too which is all I'm interested in. I have a kernel and initrd which contains a mini busybox root environment which I want to boot directly using -kernel and -initrd. Now this works fine on first start but if I reboot within the system QEMU crashes out on the next run. I used -hda /dev/zero instead of a HD image. When qemu crashes after the reboot it dumps something like this: [EMAIL PROTECTED] ~]# /usr/bin/qemu-kvm -m 1024 -smp 1 -name fedora3 -kernel vmlinuz-current -initrd initrd-diskless.img -append 'init=/init ramdisk_size=65536 root=/dev/ram0 rw' -hda /dev/zero qemu: loading initrd (0x282bde bytes) at 0x1fd7d000 exception 13 (33) rax b141 rbx 0100 rcx rdx 0100 rsi rdi rsp fff2 rbp r8 r9 r10 r11 r12 r13 r14 r15 rip 002c rflags 00033017 cs 1020 (00010200/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ds (/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) es 1000 (0001/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ss 1000 (0001/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) fs 1000 (0001/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) gs (/ p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) tr 0080 (fffbd000/2088 p 1 dpl 0 db 0 s 0 type b l 0 g 0 avl 0) ldt (/ p 1 dpl 0 db 0 s 0 type 2 l 0 g 0 avl 0) gdt fb812/30 idt 0/3ff cr0 10 cr2 0 cr3 0 cr4 0 cr8 0 efer 0 code: 00 d0 d7 1f de 2b 28 00 00 00 00 00 00 fe 00 00 00 00 02 00 -- ff ff ff 1f e8 cd 0c eb 0b 90 90 90 90 90 90 90 90 90 90 90 00 00 00 00 00 00 00 00 00 00 Is direct kernel booting just not really supported properly or is it just to do with Qemu forgetting about the direct boot kernel/initrd after a reboot?
