src/openvz_driver.c src/qemu_driver.c src/util.c src/util.h:
cleanup patches from Shuveb Hussain, with new util module for
common code shared between drivers.
Daniel
* src/hash.c, src/internal.h: Remove virGetDomainByID function
as it is not used or exported.
* src/proxy_internal.c, src/qemu_driver.c, src/remote_internal.c,
src/test.c, src/xend_internal.c, src/xs_internal.c: Fix
all callers to virGetDomain and virGetNetwork functions -
the callers do not need to set virterror since it is already
set inside the functions.
* include/libvirt/virterror.h, src/virterror.c, src/libvirt.c:
Add VIR_ERR_NO_DOMAIN and VIR_ERR_NO_NETWORK errors, which
indicate that there is no domain/network from vir*Lookup* functions.
* src/qemu_driver.c: Use VIR_ERR_NO_DOMAIN in lookup functions.
* src/test.c: Use VIR_ERR_NO_DOMAIN in lookup functions.
