Title:
qemu-img hangs on high core count ARM system
Status in QEMU:
Confirmed
Status in qemu package in Ubuntu:
In Progress
Bug description:
On the HiSilicon D06 system - a 96 core NUMA arm64 box - qemu-img
frequently hangs (~50% of the time) with this command:
qemu-img convert -f qcow2 -O qcow2 /tmp/cloudimg /tmp/cloudimg2
Where "cloudimg" is a standard qcow2 Ubuntu cloud image. This
qcow2->qcow2 conversion happens to be something uvtool does every time
it fetches images.
Once hung, attaching gdb gives the following backtrace:
(gdb) bt
