I think it is pretty horribly misleading to applications if they
leave out the VIR_DUMP_COMPRESS flag when invoking the API but
libvirt then asks for compression anyway. If an application is
only able to cope with uncompressed format then they are screwed
by the host level setting which they can't see.
Setting in qemu.conf can also be uncompressed format. The problem is when
qemu.conf is set to compressed format, but application can only deal with
uncompressed format, then "virsh dump" *need an option* to make qemu dump an
uncompressed core.
Maybe I misunderstand your comments, please correct me. Thanks!
