I wanted to pass a physical disk to vbox today as per this info, http://www.virtualbox.org/manual/UserManual.html#rawdisk and found out there is code missing to get the size of physical disks in VBoxManage; the following patch seems to work for me: Index: src/VBox/Frontends/VBoxManage/VBoxInternalManage.cpp @@ -54,7 +54,8 @@ #ifdef RT_OS_WINDOWS # include <windows.h> # include <winioctl.h> -#elif defined(RT_OS_LINUX) || defined(RT_OS_DARWIN) || defined(RT_OS_SOLARIS) +#elif defined(RT_OS_LINUX) || defined(RT_OS_DARWIN) \ + || defined(RT_OS_SOLARIS) || defined(RT_OS_FREEBSD) # include <errno.h> # include <sys/ioctl.h> # include <sys/types.h> @@ -76,6 +77,9 @@ # include <sys/dkio.h> # include <sys/vtoc.h> #endif /* RT_OS_SOLARIS */ +#ifdef RT_OS_FREEBSD +# include <sys/disk.h> +#endif /* RT_OS_FREEBSD */ using namespace com; @@ -1010,6 +1014,28 @@ vrc = VERR_INVALID_PARAMETER; goto out; } +#elif defined(RT_OS_FREEBSD) + struct stat DevStat; + if (!fstat(RawFile, &DevStat) && S_ISCHR(DevStat.st_mode)) + { + off_t cMediasize = 0; + if (!ioctl(RawFile, DIOCGMEDIASIZE, &cMediasize)) + { + cbSize = cMediasize; + } + else + { + vrc = RTErrConvertFromErrno(errno); + RTPrintf("Cannot get the block count for file '%s': %Rrc", rawdisk.raw(), vrc); + goto out; + } + } + else + { + RTPrintf("File '%s' is no character device\n", rawdisk.raw()); + vrc = VERR_INVALID_PARAMETER; + goto out; + } #else /* all unrecognized OSes */ /* Hopefully this works on all other hosts.
