[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-users] Qemu bios timeout
You have to modify the /tools/firmware/rombios/rombios.c I did some work on this based on some patches found on xen-devel. I'll attach a patch to rombios.c and a hvmloader build on 3.2.0 with rombios patches applied. Please don't look too close at this patch as this was my first try with bios routines... ;) Cheers, Stephan Nick Anderson schrieb: Does anyone know how to change the bios timeout for qemu when dealing with HVMs? Sometimes getting connected with vnc takes a bit, It would be nice to have a bit more time._______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users -- Stephan Seitz Senior System Administrator *netz-haut* e.K. multimediale kommunikation zweierweg 22 97074 würzburg fon: +49 931 2876247 fax: +49 931 2876248 web: www.netz-haut.de <http://www.netz-haut.de/> registriergericht: amtsgericht würzburg, hra 5054 --- xen-3.2-3.2.0/tools/firmware/rombios/rombios.c 2008-01-17
