I know these are mostly gamers but they have a lot of experience doing PCI pass though: https://discord.gg/du9ecG I have found them extremely helpful in the past doing libvirt PCI passthough. *Paul O'Rorke* On 2020-02-05 10:13 a.m., Jim Fehlig wrote: > On 2/4/20 1:04 AM, Christoph wrote: >> this config does not work... why? > > Without more details, I don't know why

Thank you for your reply, I'm still getting hard time to attach the hostdev, I couldn't make it work out of the doc. I took the address details from: # ll /sys/bus/scsi/devices/7:* lrwxrwxrwx 1 root root 0 Feb 8 12:58 /sys/bus/scsi/devices/7:0:0:0 -> ../../../devices/pci0000:00/0000:00:03.0/0000:08:00.1/host7/rport-7:0-0/target7:0:0/7:0:0:0 lrwxrwxrwx 1 root root 0 Feb 8 12:58

Hi, I'm trying to passthrough legacy PCI ISDN controller to a KVM based virtual machine: <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x04' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00'

Hi folks, Has anyone encountered the following PCI passthrough error? error: internal error Process exited while reading console \ log output: char device redirected to /dev/pts/1 assigned_dev_pci_read: pread failed, ret = 0 errno = 2 It's produced after I've detached the PCI device from the base OS and have tried to start up the guest domain. To get to this point, I

I don't understand the domain bus slot fuction in below xml,becase, this is used when deal with management of host devices that can be handed to guests via passthrough as <hostdev> elements in the domain XML.( from http://libvirt.org/formatnode.html) I don't see it use passthrough feature, why it has "domain" bus" slot" and function here <disk

hi laine, thx for the fast answer. i tried VFIO as it seems supported and got at least one step further. starting the guest with one of the DVB cards is possible now, even when the other card is in the hosts pci config (not removed soft or hard). adding the second card/device thru ... > <hostdev mode='subsystem' type='pci' managed='yes'> >

Hi, We try PCI Passthrough of host network devices on PPC platform. http://wiki.libvirt.org/page/Networking#Assignment_with_.3Cinterface_type.3D.27hostdev.27.3E_.28SRIOV_devices_only.29 But we got a similar issue as below that reported on RedHat before: https://bugzilla.redhat.com/show_bug.cgi?id=1040626 With <hostdev>, it could start VM successfully. <hostdev

I have a PCI sound card that I would like to assign to a VM, but when I try to do so the VM fails to start and displays this message: Error starting domain: Unable to read from monitor: Connection reset by peer Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 44, in cb_wrapper callback(asyncjob, *args, **kwargs) File

Hi Laine, Sorry to disturb you. It seemed this issue had been fixed in libvirt-1.2.2/libnl-3.2.22/linux-3.12. But we still got the error on PowerPC platform. I'll appreciate if you could give any suggestion. We are not sure if any netlink implementation in kernel space is missed. The scenario is a little complicated. We installed internal PF and VF kernel modules and want to use

hi, i have a small trouble with pci-passthrough. i have a working configuration passing a tv card into the guest, all is fine and dandy. as soon as i add my second identical card into the host i cant start the guest anymore, whether i add the second card to the guest or not. error message is identical in both cases. message of virt-manager|virsh|libvirtd.log: > libvirtError: internal error:
