hawihoney Posted October 27, 2020 Share Posted October 27, 2020 What are the steps I need to do before moving from 6.83 to 6.90? I'm talking about passthru of adapters (2x HBA for two VMs, 2x USB for two VMs, 1x GPU for docker). Currently on 6.83 I have possibly redundant settings as follow: 1.) /boot/syslinux/syslinux.cfg: xen-pciback.hide (hide both HBAs, this one redundant?) [...] label unRAID OS menu default kernel /bzimage append xen-pciback.hide=(06:00.0)(81:00.0) initrd=/bzroot [...] 2.) /boot/config/vfio-pci.cfg: BIND (hide both HBAs, or this one redundant?) BIND=06:00.0 81:00.0 3.) First VM: 1x HBA, 1x USB [...] <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x06' slot='0x00' function='0x0'/> </source> <alias name='hostdev0'/> <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x0930'/> <product id='0x6544'/> <address bus='2' device='4'/> </source> <alias name='hostdev1'/> <address type='usb' bus='0' port='1'/> </hostdev> [...] 4.) Second VM [...] <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x81' slot='0x00' function='0x0'/> </source> <alias name='hostdev0'/> <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x8564'/> <product id='0x1000'/> <address bus='2' device='10'/> </source> <alias name='hostdev1'/> <address type='usb' bus='0' port='1'/> </hostdev> [...] What do I need to remove/add before booting with the new 6.90 system? Thanks in advance. Quote Link to comment
letrain Posted April 27 Share Posted April 27 this is an old post but best i could find for xen-pciback.hide , what did you end up doing? Quote Link to comment
SpaceInvaderOne Posted April 30 Share Posted April 30 The xen-pciback.hide parameter is not necessary to "stub" PCI devices for passthrough. Instead, you can simply bind them to VFIO, which can be done directly from the GUI. To do this, navigate to Tools > System Devices, and select the devices you want to passthrough by ticking the box next to each. After rebooting your system, these devices will appear in the VM template, ready for use Quote Link to comment
