Re: Query related with Emulation on QEMU

No, No, Yes Sadly, there seems to still be no IA64 CPU emulation in Qemu (even the ability to run QEMU on actual IA64 hardware has been removed) or anywhere else, forcing all but the richest companies to not develop IA64 software while the architecture existed. For SunOS, look at the x86/x64

Re: qemu-img convert: Compression can not be disabled when converting from .qcow2 to .raw

Dear Sven, Note that qcow2 files contain data saying how large the virtual disk is and what blocks in the virtual disk correspond to what blocks in the qcow2 file. Thus adding extra all-0 blocks at the end of a qcow2 file using generic file manipulation tools like truncate or dd will not cha

Only if the BIOS matches the virtual motherboard provided by Qemu . For example, if the BIOS tries to configure a register controlling the USB controller on the real motherboard, it will only work if the virtual motherboard has the same USB controller at the same bus address. The Qemu virtual
