[arch-general] Xen GPU Passthrough
by Jay Seth 10 Nov '16

10 Nov '16

Hello, I need help & I would appreciate any help to get my setup working. When I try to start a domU on Arch/Xen, I am getting the following error: xl create w7.cfg Parsing config from w7.cfg libxl: error: libxl_pci.c:1235:libxl__device_pci_add: PCI device 0:1:0.0 is not assignable libxl: error: libxl_create.c:1566:domcreate_attach_pci: libxl_device_pci_add failed: -3 libxl: error: libxl.c:1583:libxl__destroy_domid: non-existant domain 2 libxl: error: libxl.c:1542:domain_destroy_callback: unable to destroy guest with domid 2 libxl: error: libxl.c:1471:domain_destroy_cb: destruction of domain 2 failed Checking the GPU with lspci, I get: 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF108M [GeForce GT 525M] [10de:0df5] (rev a1) Subsystem: Dell Device [1028:0446] Kernel driver in use: nouveau Kernel modules: nouveau Background... I am relatively new to Arch and Xen (coming from Fedora and KVM) but I decided to see if Xen on Arch would support GPU passthrough for my Dell XPS 15z. It has Nvidia GeForce GT 525M. On Fedora/KVM, GPU passthrough works but there is the nasty error code 43. So that proved that the GPU can be passed through. I am trying Xen to see if the HVM will hide whatever it is that Nvidia uses to identify a VM platform and then disable drivers, giving error code 43. I have successfully installed xen and created a test VM. The config is as follows: name = 'w7' builder = 'hvm' vcpus = '2' memory = '2048' boot = 'd' on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'destroy' device_model_version = 'qemu-xen-traditional' disk = [ '/home/tim/Downloads/w7.iso,,hdc,cdrom', '/home/tim/vms/w7/w7.img,raw,hda,rw' ] vif = ['mac=00:16:3e:54:86:18,bridge=xenbr0'] acpi = '1' apic = '1' serial = 'pty' localtime = 1 # Keyboard and mouse passthrough usb = '1' usbdevice = ['tablet'] # VGA and sound passthrough viridian = '1' xen_platform_pci = '1' gfx_passthru = '1' pci_permissive = '1' pci = ['01:00.0,rdm_policy=relaxed'] # Remote vnc access vnc = '1' # vnclisten = 'x.x.x.x' The BDF of the GPU is 01:00.0 and it is what I have set for the pci parameter. I have also set intel_iommu=on in my /etc/default/grub file. I am booting the Xen kernel. I have also set the vfio-pci id for the GPU in /etc/modprobe.d/vfio.conf as: options vfio--pci ids=10de:0df5 After that, I set the vfio modules to load first in /etc/mkinitcpio.conf as follows: MODULES="vfio vfio_iommu_type1 vfio_pci vfio_virqfd i915 nouveau" HOOKS="base udev autodetect modconf block filesystems keyboard fsck" After that, I did: mkinitcpio -p linux grub-mkconfig -o /boot/grb/grub.cfg reboot After reboot, I ran the following checks: dmesg | grep vfio [ 3.856580] vfio-pci: probe of 0000:01:00.0 failed with error -22 [ 3.856584] vfio_pci: add [10de:0df5[ffff:ffff]] class 0x000000/00000000 [ 18.960859] xen_pciback xen_netback xenfs xen_privcmd xen_blkback xen_gntalloc xen_gntdev xen_evtchn ip_tables x_tables ext4 crc16 jbd2 fscrypto mbcache sd_mod serio_raw atkbd libps2 ahci libahci xhci_pci xhci_hcd libata ehci_pci ehci_hcd scsi_mod usbcore usb_common i8042 serio nouveau mxm_wmi wmi ttm i915 video button intel_gtt i2c_algo_bit drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops drm vfio_pci irqbypass vfio_virqfd vfio_iommu_type1 vfio dmesg | egrep -i iommu [ 0.000000] Command line: /boot/vmlinuz-linux root=UUID=d8ee1f55-14c6-4401-bc22-24b78eaf8863 rw intel_iommu=on quiet console=tty0 [ 0.000000] Kernel command line: /boot/vmlinuz-linux root=UUID=d8ee1f55-14c6-4401-bc22-24b78eaf8863 rw intel_iommu=on quiet console=tty0 [ 0.000000] DMAR: IOMMU enabled [ 18.960859] xen_pciback xen_netback xenfs xen_privcmd xen_blkback xen_gntalloc xen_gntdev xen_evtchn ip_tables x_tables ext4 crc16 jbd2 fscrypto mbcache sd_mod serio_raw atkbd libps2 ahci libahci xhci_pci xhci_hcd libata ehci_pci ehci_hcd scsi_mod usbcore usb_common i8042 serio nouveau mxm_wmi wmi ttm i915 video button intel_gtt i2c_algo_bit drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops drm vfio_pci irqbypass vfio_virqfd vfio_iommu_type1 vfio Is it possible that the root of the problem might the vfio-pci error -22 at boot?

[arch-general] Cannot no longer resolve local hostname with the new nsswitch.conf
by Chi-Hsuan Yen 08 Nov '16

08 Nov '16

Hi Arch enthuasiasts, With testing/filesystem 2016.11-2, I can no longer use my local hostname to acess services on the local machine. For example: $ hostname PC12574 $ ping PC12574 ping: PC12574: Name or service not known Seems changes in nsswitch.conf [1] does the effect. If I change the hosts: line in nsswitch.conf back to the old configuration "files resolve mymachines myhostname", or remove the [!UNAVAIL=return] part from this line, ping works fine: $ ping PC12574 PING PC12574(PC12574 (fe80::ae22:bff:fe77:e20b%enp3s0)) 56 data bytes 64 bytes from PC12574 (fe80::ae22:bff:fe77:e20b%enp3s0): icmp_seq=1 ttl=64 time=0.025 ms 64 bytes from PC12574 (fe80::ae22:bff:fe77:e20b%enp3s0): icmp_seq=2 ttl=64 time=0.078 ms Is it a bug? Or such a usage is just a non-standard coincidence? Thanks for any help. Yen Chi Hsuan [1] https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/fil…

[arch-general] kernel linux-4.8.6-1-x86_64 not able to load modules
by Anast Gramm 05 Nov '16

05 Nov '16

Hey list, After, as suggested in arch-annoucne, I force-upgrated ttf-dejavu I made a full system upgrade with pacman -Syu. This installed the latest linux kernel. (the one in the subject line) The initram was completed successfully and I procceded to reboot. Then Xserver would complain about my intel module (i915) After a while I figured that nothin was loaded. I had no internet connection (ip link would only show loopback), when I plugged a USB drive the kernel woudln't detect it, and so on... I downgraded to linux-4.8.4 using arch live with arch-chroot. Everything works but when I upgrade to the latest kernel the same thing happens. Since I am prety new to the linux power user world, I have no idea what to do next. Should I file a bug? Ad if yes how do I do that? Also about the kernel upgrade, should I just skip 4.8.6 and get the next one? Since I didn't see anything in the list about linux-4.8.6 I guess it must have something to do with my setup. Any suggestions will be really helpful!

[arch-general] Almost system crash, users getting logged out
by J. C. 05 Nov '16

05 Nov '16

Hi list, I had an "almost crash" last night. When I got up in the morning, the session on the first six TTYs were closed, but the sessions on TTY 8-10 were still open. Having taken a look at the journal, I found a lot of activity around 4AM. That may have been preceeded by something around midnight, when my music player suddenly quit, the system informing me, that there was not enough memory. A restart of the music player was successful though. I don't have any remote login services active and this sort of thing hasn't happened before, not on Arch since my installation a few weeks ago nor on the previous system. My kernel version is 4.8.2, not having rebooted since the last upgrade. The journal excerpt with the potential problem is here: https://freeshell.de/~silvain/journal.log I'd be grateful for any help and of course eagre to supply any further info to solve this issue. Thank you and best wishes Jeanette -------- When you need someone, you just turn around and I will be there <3

[arch-general] Getting Groove to Work Properly Under Arch?
by Hunter Jozwiak 05 Nov '16

05 Nov '16

Hi, I am not sure if anyone has been having a similar issue, so here goes. I recently signed up for Groove Music so that i can have a cross- platform means of accessing my collection (primarily from my Arch box and the Xbox). I have discovered that there is a Groove web client so this should, in theory work. But practice, at the current moment, is not equal to theory; I am getting an error about how Groove can't play a particular song. Before, I was getting an error about how Flash is required, so I've installed the flashpluggin package. This is where I stand now. Does anyone have any pointers to a resolution? -- Regards, Hunter Jozwiak
