Commit 6700062 introduced a jump to error which skipped the initialization of def: qemu/qemu_parse_command.c:1870:9: error: variable 'def' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized] if (!(qemuCaps = virQEMUCapsCacheLookup(capsCache, progargv[0]))) Initialize def to fix this warning and qemuCaps, to prevent a future error like this.
