similar to: xen and libvirt

Hi I need the e820_host option for a passthrough of an digitaldevices dvb-s2 card. Without this I'cant initialize the card in the domU. On an all my domU's with high IO load like an file server I need to set max_grant_frames = 64 or higher. Without this I get a lot of messages on dom0/domU and kernel exceptions. I've read it should be ok to set it = 256 on all domU's

Currently, those settings are not supported by libvirt. Do you need to adjust them for PCI passthrough to PV domains? I took a quick peek at xl.cfg(5) and based on the description of those settings

Hi Does someone know how it is possible these parameters: e820_host max_grant_frames to set with libvirt xml config? I use them with xl config but I want to change to libvirt config/tools. (with libvirt 4.10 it is possible to start pvh domains) -- ------ Greetz

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

This patch validates feature dependencies during probe and fail the probing if a dependency is missed. This fixes the issues of hitting BUG() when qemu fails to advertise features correctly. One example is booting guest with ctrl_vq=off through qemu. Cc: Rusty Russell <rusty at rustcorp.com.au> Cc: Michael S. Tsirkin <mst at redhat.com> Cc: Cornelia Huck <cornelia.huck at

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

Good afternoon xen users. I am passing through a Mellanox Infiniband virtual function device into a Paravirtualised guest under xen 4.1.x When the guest has <= 2GB of RAM it works perfectly. If I increase the RAM to > 2GB it fails to initialize. [ 7.999791] pci 0000:00:00.1: [15b3:1004] type 00 class 0x028000 [ 8.000989] pci 0000:00:00.1: reg 0x18: [mem 0xbe000000-0xbe7fffff 64bit

Hi, I am trying to plot a time serie of six colum of data sets on one plot but with using a different y-axis ranges for each - preferably with one shown on each side of the graph. I'm trying with axis function but not good luck i will for each they plot with our proper scale and range for example time A B C...etc 08:00:01 1000 15 2 08:00:02 2200 17 5 08:00:03 2500 19
