|
|
\- qemu wrapper connecting UNIX domain socket to file descriptor
|
|
|
|
.SH SYNOPSIS

.B qrap
|
|
[\fIFDNUM\fR \fIQEMU_CMD\fR] [\fIQEMU_ARG\fR]...
|
|
.SH DESCRIPTION
|
|
\fBqrap\fR is a wrapper, designed specifically for usage with \fBqemu\fR(1) and
|
|
\fBpasst\fR(1), connecting a UNIX domain socket to a file descriptor, and
|
|
running \fBqemu\fR(1) with given arguments.
|
|
|
|
A running instance of \fBpasst\fR(1) is probed checking for UNIX domain sockets,
|
|
answering a dummy ARP request, with names starting from
|
|
\fI/tmp/passt_1.socket\fR up to \fI/tmp/passt_64.socket\fR.
|
|
|
|
If first and second arguments are not a socket number and a path, that is,
|
|
respectively, \fIFDNUM\fR and \fIQEMU_CMD\fR, \fBqrap\fR will try to locate a
|
|
qemu binary and patch the command line to specify a network device and a
|
|
\fInetdev\fR back-end for usage with \fBpasst\fR(1).
|
|
|
|
If \fBqrap\fR patches the command line, it will remove any potentially
|
|
conflicting network device, that is, any \fI-netdev\fR or \fI-net\fR option, or
|
|
any \fI-device\fR option with argument starting with \fIvirtio-net-pci,\fR,
|
|
\fIvirtio-net-ccw,\fR, \fIe1000,\fR, \fIe1000e,\fR, or \fIrtl8139,\fR.

.SH NOTES
|
|
|
|
This wrapper is temporary and needed only as long as \fBqemu\fR(1) does not
|
|
directly support a UNIX domain socket as \fInetdev\fR back-end.
|
|
|
|
Out-of-tree patches for \fBqemu\fR(1) introducing support for a UNIX domain
|
|
socket back-end are available at:
