I don't know why Solaris x86 10 doesn't work. add ,atapi-cd-dma-enabled=0 to the boot line when installing. The QEMU IDE controller doesn't implement DMA (or dma correctly). If you don't give a Solaris VM enough memory, the installer (java) will coredump, and it appears that it's running out of memory. Once you've got Solaris 10 X86 installed, you'll need to get the Disk Update from http://tools.de/solaris/itu/DU.zip. Normally you could do an Install Time Update to add this driver disk, but Qemu doesn't implement a floppy in ACPI (I'm testing patches now to see if that fixes the problem), and some folks are working on OpenSolaris to fix the enumeration of the floppy on the emulated ISA bus (or when -no-acpi is called). So the trick to getting the NIC driver into Solaris 10x86 is to call QEMU with the DU.img as hdd. Then once Solaris is booted, you do the following: mount -F pcfs /dev/dsk/c1d1p0:c /mnt cd /mnt/DU/210/i86pc/Product cp ni.Z /var/tmp uncompress ni.Z cpio -idvm ni pkgadd -d . CSWni At this point, it's probably easier just to do a sys-unconfig so that Solaris 10/x86 with redo it's networking for DHCP.

Not really. POSIX doesn't mandate that ftruncate() increase a file
size. This is a Linux-ism and is only valid for filesystems that
support holes (which vfat doesn't).

Ok, so in that case this is something qemu-img should handle on its own then.
(Since we're not likely to see a fix in either glibc or the kernel for this,
and it has the potential to be a portability issue.)

Turns out I was wrong about this too.
