Hello folks, since a couple of days Im intensively trying to get around with Xen - so far I've been successful. Xen is really complex, I've just figured out that there are two APIs - one which is obsolete (xend/xm) the other one which is newer/current (XL). In fact I had already read about it, but what I did not know was that the XL API is not able to utilize VGA Passthru, why is this? When I try it, exacly same box, hardware, kernel everything - upon xl create ... I get an obscure error message: libxl: error: libxl_pci.c:990:libxl__device_pci_reset: The kernel doesn't support reset from sysfs for PCI device 0000:03:00.0 I was recompiling my kernel like 6 times until I figured out, there is no option I did forget - its not about the Linux Kernel. (I was suprised before I had it running prior the upgrade to Xen 4.4.0 (Gentoo repos)) So I did back downgrade to 4.3.2 in order to get xend/xm again and voila - with xm create I do not get this messages. So all I want to know is, why is this? What is the difference - is it simply not implemented yet? Will it be implemented? Or am I still doing something wrong? And can I use both, lets say for VMs where I do not need passthru, I use XL tools - for the other VM I use XM? - As far as I know xm/xl produce the same outputs literally. regards, Georg _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
