The -sdl and -net ...name=XXX arguments were both introduced in QEMU 0.10, so the QEMU driver can assume they are always available.
The -sdl wasn't really removed it seems - although it did me peeking into the rabbit hole for a make check failure...
After a bit of debugging - qemuParseCommandLine has the following:
} else if (STRPREFIX(arg, "-hd") || STRPREFIX(arg, "-sd") || STRPREFIX(arg, "-fd") || STREQ(arg, "-cdrom")) { WANT_VALUE();
If I add:
} else if (STREQ(arg, "-sdl")) { /* Ignore */
Just before that, then things are happy again.
Rather than ignoring it, I added this:
virDomainGraphicsDefPtr sdl; if (VIR_ALLOC(sdl) < 0) goto error; sdl->type = VIR_DOMAIN_GRAPHICS_TYPE_SDL;
This seems to duplicate an allocation later :
if (!nographics && def->ngraphics == 0) {
That deals with case where QEMU would previously default to SDL if no args are listed. If you specified '-vnc blah -sdl' it would not trigger though, so we need to improve that.
It's also not FREE'd or appended to def->graphics
Sigh, so how about this instead, so we just explicitly trigger the existing SDL codepath: diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index c016d43..792ada3 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -12759,6 +12759,7 @@ qemuParseCommandLine(virCapsPtr qemuCaps, qemuDomainCmdlineDefPtr cmd = NULL; virDomainDiskDefPtr disk = NULL; const char *ceph_args = qemuFindEnv(progenv, "CEPH_ARGS"); + bool have_sdl = false; if (pidfile) *pidfile = NULL; @@ -12982,10 +12983,7 @@ qemuParseCommandLine(virCapsPtr qemuCaps, goto error; } } else if (STREQ(arg, "-sdl")) { - virDomainGraphicsDefPtr sdl; - if (VIR_ALLOC(sdl) < 0) - goto error; - sdl->type = VIR_DOMAIN_GRAPHICS_TYPE_SDL; + have_sdl = true; } else if (STREQ(arg, "-m")) { int mem; WANT_VALUE(); @@ -13672,7 +13670,7 @@ qemuParseCommandLine(virCapsPtr qemuCaps, VIR_FREE(capsdata); } - if (!nographics && def->ngraphics == 0) { + if (!nographics && (def->ngraphics == 0 || have_sdl)) { virDomainGraphicsDefPtr sdl; const char *display = qemuFindEnv(progenv, "DISPLAY"); const char *xauth = qemuFindEnv(progenv, "XAUTHORITY"); Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
