I’d try: (gdb) target remote localhost:1234 (gdb) continue Using the ‘-s’ option makes qemu listen on port tcp::1234, which you can connect to as localhost:1234 if you are on the same machine. Qemu’s ‘-S’ option makes Qemu stop execution until you give the continue command. Best thing would probably be to have a look at … Read more
This is permitted in GNU as an obscure extension to C 5.7 Conditionals with Omitted Operands The middle operand in a conditional expression may be omitted. Then if the first operand is nonzero, its value is the value of the conditional expression. Therefore, the expression x ? : y has the value of x if … Read more
You can compile qemu for youself and install it into your home directory. There will be no kernel-mode qemu accelerator, but the qemu will work and the speed will be rather high. Qemu has two options for non-gui start: http://wiki.qemu.org/download/qemu-doc.html 2.3.4 Display options: -nographic Normally, QEMU uses SDL to display the VGA output. With this … Read more
First, install QEMU. On Debian-based distributions like Ubuntu, run: $ apt-get install qemu Then run the following command: $ qemu-img convert -O vmdk imagefile.dd vmdkname.vmdk I’m assuming a flat disk image is a dd-style image. The convert operation also handles numerous other formats. For more information about the qemu-img command, see the output of $ … Read more
QEMU is a powerful emulator, which means that it can emulate a variety of processor types. Xen uses QEMU for HVM guests, more specifically for the HVM guest’s device model. The Xen-specific QEMU is called qemu-dm (short for QEMU device model) QEMU uses emulation; KVM uses processor extensions (HVM) for virtualization. Both Xen and KVM … Read more
Most current hypervisors that run on Intel hardware use CPUID leaves 0x40000000 et seq. to pass information about the hypervisor from host to guest. KVM, Xen, VMware and Hyper-V all use this method. This is in addition to the hypervisor feature flag set in CPUID leaf 0x1, which indicates that the machine is a virtual … Read more
First, create a raw image of the required size. I’ll assume 10G is enough. Using seek creates a sparse file, which saves space. dd if=/dev/null of=example.img bs=1M seek=10240 Next, create a filesystem on it. mkfs.ext4 -F example.img (Note that you need the -F option for mkfs.ext4 to operate on a file as opposed to a … Read more
Basically both have features which the other does not have, so this might ease the decision. QEMU/KVM is better integrated in Linux, has a smaller footprint and should therefore be faster. VirtualBox is a virtualization software limited to x86 and amd64 architecture. Xen uses QEMU for the hardware assisted virtualization, but can also paravirtualize guests … Read more

You probably need to make a label on the disk first. Try just running parted manually: parted /dev/hda unit GB mklabel msdos mkpartfs primary ext3 0 5
