Folllowing the instructions at https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF I can successfully pass through devices to windows running under virt-manager. In the nvidia GPU case I...

oh, there is much much much code,it's too too too hard for me. So,,,,,can i ask more question:use virt-manager create a domain,but with a result of "unsupported configuration:the ioh3420 controller is not supported in this qemu".since it's arm64 platform,and ioh3420 is a intel device.right?Why produce a intel device in arm64 platform? So, can i delete the ioh3420 only by changing the code?info: i use the libvirt-2.0.0,virt-manager create doamin succeed;when i update to li...

I don't think there's a way to step into virt-manager's process of defining domains. However, you can use virt-install directly...

Greetings all, I have a host machine that runs a router within a vm. I want to allow a connection between the host and the guest so the host can connect to the lan provided by the router vm. I've created a dummy interface with these commands: $ ip link add ens99-dummy type dummy $ ip link set ens99-dummy address 52:54:00:1f:d0:ff this resulted with this output: $ ifconfig ens99-dummy

Thanks for your reply what i want to know is that why there are many devices in $domain.xml, actully , i choose nothing in virt-manager? so, Do i need to look at qemuDomainDefineXMLFlags()? hours ago, i thought it's qemuDomainCreateWithFlags. -- Have a good day > -----原始邮件----- > 发件人: Michal Privoznik <mprivozn@redhat.com> > 发送时间: 2018年4月26日 星期四 > 收件人: "李卓瑶"

Hey All, I've been googleing this issue for hours but I can't find a workable solution. I found a reply to a bug posting that said the USB hub on the VM defaults to USB 1.1. I see this is true when I lsusb on the CentOS 7 guest. The reply to the bug post went on to say that the problem is that the USB 2.0 camera will not work with the USB 1.1 default hub and that I should change the

...uest, but perhaps logging access to the emulated bridge is already sufficient. The Prefetchable Base Upper 32 Bits register is at offset 0x28. In a trace where the Nvidia device is disabled/enabled via Device Manager, I see writes on the enable path: 2571 at 1535108904.593107:rp_write_config (ioh3420, @0x28, 0x0, len=0x4) For Linux, I only see one write at startup, none on runtime resume. I did not test system sleep/resume. (disable/enable is arguably a bit different from system s/r, you may want to do additional testing here.)
