Re: [libvirt] [PATCH 7/8] qemu: Resolve Coverity BAD_SIZEOF

Coverity complains about the calculation of the buf & len within the PROBE macro. So to quiet things down, do the calculation prior to usage in either write() or qemuMonitorIOWriteWithFD() calls and then have the PROBE use the calculated values - which works.
