I am looking for some help.
Any time I add a third video card to the system the host system xwindows will crash at random times and drop me to the command prompt. I do not start in Xwin. Sometimes I can restart with startx sometimes I have to reboot. Hard power restart. The primary card for the host system is a Nvidia K620 4k output The first passthru card for Win7 VM is an Nvidia k4200 4k output The third card is one of three that I have tried Nvidia K2000 or M4000 or AMD W5100 (any one of these cause a crash in the host Xwindows) Mother board is a supermicro X10SRA-F I had the same problem with an ASUS X99 Deluxe CPU XEON 1630 V3 Also tried with an I7-5960 64GB 2133 ecc memory OS Fedora 25 4.10.13-200.fc25.x86_64 I am using the Nvidia driver for Xwin on the host machine. I have 4 VM's in the background two Ubuntu linux and two win7 The K4200 is attached to one of the win7 machines. My grub file: GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rhgb quiet intel_iommu=on pci-stub.ids=10de:11b4,10de:0e0a,1 0de:13ba,10de:0fbc rd.driver.blacklist=nouveau" GRUB_DISABLE_RECOVERY="true" [jim@localhost ~]$ more /etc/sysconfig/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rhgb quiet intel_iommu=on pci-stub.ids=10de:11b4,10de:0e0a,10de:13ba,10de:0fbc rd.driver.blacklist=nouveau" GRUB_DISABLE_RECOVERY="true" Jim
