Description:
Trying to run qemu with exec qemu-system-x86_64 -m 3000 -M q35 -usb -cpu host -accel kvm -smp 4,sockets=1,cores=4,threads=1 -device usb-kbd -device usb-mouse -nic user -rtc base=localtime -boot c -drive file=W10.img,id=disk,format=raw (where W10.img is just a stock Windows 10 install, but this also happens with other images like ubuntu) freezes/locks up/crashes, sometimes before qemu BIOS, sometimes while booting up the guest OS. often requires sigkill to recover. seems to be "caused" by compiling with GCC. compiling with clang appears to "fix" it. Additional info: * package version(s) 7.2.0-3 * config and/or log files etc. N/A * link to upstream bug report, if any N/A Steps to reproduce: exec qemu-system-x86_64 -m 3000 -M q35 -usb -cpu host -accel kvm -smp 4,sockets=1,cores=4,threads=1 -device usb-kbd -device usb-mouse -nic user -rtc base=localtime -boot c -drive file=W10.img,id=disk,format=raw (might have to try a few times, it's a bit inconsistent) |
This task depends upon

Cannot repro. My win10 VM's work perfectly. QEMU is working fine
for literally thousands of Arch users so I'd suggest the cause of
your problems lies elsewhere. Are you using QEMU from the official
Arch repo?
Yes. How are you running your VMs?
Please use the proper support channels for support

problems that are apparently only applicable to you.
