So, I update Gigabyte BIOS and xen 4.1. Visually, BIOS works fine, with no bad IVRS table: https://docs.google.com/document/d/1d3-exPg8aeJHUj64CcxTxONQUkWqHmMZMdsBD6XaSSc/edit?usp=sharing xm create winxp: Using config file "./winxp". Error: (22, ''Invalid argument'') winxp file content in link upper. Also, I tried to start xen-4.2, with same config with commented line #vif = [ ''bridge=xenbr0'' ] VM start successfully, but without radeon card and usb controller,now. I.e w/o passthrought. grub option xen-pciback.hide="(05:00.0)(05:00.1)(02:00.0)" not work in 4.2? But lspci says, that devices properly owned by pci-stub driver: "Kernel driver in use: pci-stub" _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
