[Qemu-devel] big hidden file

[Marc Collin]

hi 
 
 i use suse 9.2, qemu 0.62 and kqemu. 
 
 in the documentation of kqemu we can read 
 
 "When using KQEMU, QEMU will create a big hidden file containing the RAM of 
the virtual machine. For best performance, it is important that this file is 
kept in RAM and not on the hard disk. QEMU uses the `/dev/shm' directory to 
create this file because tmpfs is usually mounted on it (check with the shell 
command df). Otherwise `/tmp' is used as fallback. You can use the 
QEMU_TMPDIR shell variable to set a new directory for the QEMU RAM file."
