Comment 2 Michal Privoznik 2021-02-12 17:01:00 UTC

Merged upstream as:

859f7e2072 qemu_shim: URI escape root directory

v7.0.0-448-g859f7e2072

Comment 6 yafu 2021-05-26 08:20:29 UTC

Verified with libvirt-daemon-7.3.0-1.module+el8.5.0+11004+f4810536.x86_64.

Test steps:
1.Start a guest by 'vrit-qemu-run' with a root dir containing space char:
# virt-qemu-run  -v /root/vm1.xml -r /tmp/test\ test/
virt-qemu-run: 79: initializing libvirt 8910
virt-qemu-run: 2668: initializing signal handlers
virt-qemu-run: 2783: preparing event loop thread
virt-qemu-run: 2873: opening qemu:///embed?root=%2Ftmp%2Ftest%20test%2F
virt-qemu-run: 39346: fetching guest config /root/vm1.xml
virt-qemu-run: 39457: starting guest /root/vm1.xml
virt-qemu-run: 1086625: guest running, Ctrl-C to stop now

2.Check the qemu process and could see the qemu process started by step 1:
# ps aux | grep -i qemu-kvm
qemu        8935 95.0  1.2 5397352 797228 ?      SLl  04:19   0:36 /usr/libexec/qemu-kvm -name guest=vm1,debug-threads=on -S -object {"qom-type":"secret","id":"masterKey0","format":"raw","file":"/tmp/test test//lib/qemu/domain-1-vm1/master-key.aes"} -machine pc-q35-rhel8.4.0,accel=kvm,usb=off,smm=on,dump-guest-core=off,...
