Description of problem:
look at a running QEMU instance which has the --mem-path arg set, and it'll have an open handle to /proc/meminfo
# lsof -p `pgrep qemu-kvm` | grep proc
qemu-kvm 6667 qemu 7r REG 0,3 0 4026531986 /proc/meminfo
The flaw is obvious in vl.c
static int gethugepagesize(void)
THis method opens /proc/meminfo, but leaks the FD never bothering to close it
Version-Release number of selected component (if applicable):
Steps to Reproduce:
