The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/o...

Hi folks There are two components, which are currently not included in the main utils package: ioemu, xenfb. ioemu is currently shipped in its own package, xenfb is not shipped at all. Should we fold them into the main utils package for simplicity? ioemu adds 300k to the package and 4300k in one dependency (libsdl1.2debian). xenfb adds another 200k to the package and 200k in one dependency (libjpeg62)....

...ms to work fine, saving computations and communications. I''m now wondering about the interface: it looks to me like it could be as simple as a "refresh-period" node in the backend part of XenStore: the front-end would watch it, and update the timing of its internal refresh loop, xenfb_fps in the case of Linux'' xenfb for instance. A period of 0 would mean that no refresh is needed (e.g. minimized window) Samuel _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

...to implement them all twice is not very desirable. Also libvncserver code is terrible - many bad thread race conditions that are near impossible to diagnose, let alone solve :-( At the summit there were a couple of suggestions, either taking the VNC server code from QEMU and splicing it into the xenfb daemon. Another was to take the QEMU VNC code and put it into a library that can be used by both QEMU & xenfb. Neither of those is a particularly appealing prospect. Then Anthony Liguori suggested a 3rd approach, which was to add a new QEMU machine type to the x86 target, and simply disable al...

Hi, I''m trying to start Xorg on a PV Fedora8 guest running 2.6.21.7 fedora stock xen kernel, however, it seems that there''s no xenfb.ko driver included in the .rpm package.

After some changes resulting in the irq (since used as an array index) to be converted to unsigned int, we''re observing oopses resulting from xenfb calling notify_remote_via_irq() with -1 as the irq argument. Clearly, the two possible simple work-arounds would be to either make the event channel code always tolerate and ignore invalid irq inputs or to prevent the call to notify_remote_via_irq() in xenfb in that case. Neither would fix the root...

Hi all, I''m trying to expand the screen resolution of my guest when using vnc. It appears I need to use the extra variable in my guest config file and xenfb. I pass it in like this: extra = ''xenfb.video=8,1024,768'' I can see this being passed to the kernel when it boots but it doesn''t change the vnc screen resolution. I also see this when I type ps -ef | grep vnc # ps -ef | grep vnc root 7187 2103 0 10:18 ?...

...o shutdown the guest domains since it never realizes they have halted. Ultimately I can shut them down then destroy them but this seems like a bug. This is probably not a bug but just more a question. I'd like to expand the resolution for my vnc connection. I've added "extra = 'xenfb.video=8,1024,768'" to my guests config file but it never recognizes it. Is there another way I should be doing this? Thanks for all the hard work!
