Hi everyone,
I am looking into using the new Data Streaming Accelerator (DSA)
hardware acceleration feature built into the Intel Sapphire Rapids
system. One of the scenarios I am investigating is the QEMU live
migration feature. I noticed that during live migration, there is
pretty busy work

Hi,
After pulling in the QEMU latest commits, I can no longer run the
"configure" command. Below is the error message I am seeing. I believe this
is related to this change "configure: create a python venv
unconditionally".
I am running on Debian GNU/Linux 11 (bullseye) and 5.15 kernel version.
