Hi,

I'm trying to write a vioblk driver for Solaris. I've gotten it to the point
where the devices are visible to Solaris and can create and FDISK partition
table and label it.

However, when I try an use newfs to create a filesystem, the VM crashes with the
following in the log

*** glibc detected *** /usr/bin/qemu-kvm: double free or corruption (!prev):
0x00007fda4c000a00 ***
======= Backtrace: =========
/lib64/libc.so.6[0x3d6da76d63]
/usr/bin/qemu-kvm[0x43d6ce]
/lib64/libpthread.so.0[0x3d6e206ccb]
/lib64/libc.so.6(clone+0x6d)[0x3d6dae0c2d]

I'm using qemu-kvm-0.14.0-4.fc14.x86_64

Any suggestions on how to debug this?

Thanks,
Conor
