[PATCH v2] kvm tools: add HOME env var to hostfs

Add a HOME env var when booting a hostfs guest. This will point out to a home dir within the given guest name. This will make several apps happier when being run under hostfs. Signed-off-by: Sasha Levin levinsasha...@gmail.com --- tools/kvm/builtin-setup.c | 1 + tools/kvm/guest/init.c| 5
