Dual head across two systems using SPICE

2020-03-20 Thread James Le Cuirot
Hello, My new work situation has meant that I'm using QEMU, cross-compiled from Gentoo, on a Windows 10 host laptop but connecting via SPICE from another Linux desktop. I also use Barrier to share input between the two machines and ideally I'd like to have the laptop showing a second QEMU display.

Hello Jérôme, just want to give a +1. But have the exact issue you described with network i/o. If i try to transfer a big file from a samba share (at around 40MB/s~) the VM is freezing. Nearly identical configuration to yours. Greetings Th3R3al Am 20.03.20 um 20:46 schrieb Jérôme Poulin: > Hi e

Clarification:  Both qemu.org and www.qemu.org need (but lack) SPF records. Steps to reproduce: $ host -t TXT qemu.org qemu.org has no TXT record $ host -t TXT www.qemu.org www.qemu.org is an alias for qemu.org. Expected output (if no @qemu.org e-mail addresses): $ host -t TXT qemu.org qemu.org

I would like to ask a question about QEMU

Hi, guys:  Q: does qemu now support VHE virtualization with arm64 kernel enabled? Can I build a qume-system-arm64 executable with VHE support for my particular device?   Looking forward to your reply.

COLO's iperf3 test leads to "KVM: entry failed, hardware error 0x80000021" and segmentation fault

Hello, guys I was testing QEMU-4.2.0's COLO using iperf3. Primary VM is an iper3 receiver, and the client is an iperf3 sender. PVM host information: model name : Intel(R) Core(TM) i5-4590S CPU @ 3.00GHz Linux 5.0.0-38-generic #41-Ubuntu SMP Tue Dec 3 00:27:35 UTC 2019 x86_64 x86_64 x86_64
