My team builds several amd64 and arm64 Linux container images daily and lately we’ve been having trouble with the CentOS 7 arm64 build hanging. Our build machine is an amd64 Ubuntu Openstack machine running Docker and we use QEMU to run
arm64 containers. We recently upgraded tooling to:
binfmt-support/jammy,jammy,now 2.2.1-2 amd64 [installed] qemu-guest-agent/jammy-updates,jammy-updates,now 1:6.2+dfsg-2ubuntu6.12 amd64 [installed] qemu-user-static/jammy-updates,jammy-updates,now 1:6.2+dfsg-2ubuntu6.12 amd64 [installed]
qemu/jammy-updates,jammy-updates,now 1:6.2+dfsg-2ubuntu6.12 amd64 [installed] We start the container with the centos:7 image which looks like it’s 18 months old. The problem first manifested when doing
apt upgrade -y in a CentOS 7 arm64 container and I’ve tracked it down to this command command: /lib64/ld-2.17.so --verify /usr/bin/true The command seems to be taking over the CPU: [root@83d610f0f031 /]# ps -e -o pid,ppid,etime,time,state,args PID PPID ELAPSED TIME S COMMAND 1 0 40:35 00:00:00 S /usr/libexec/qemu-binfmt/aarch64-binfmt-P /bin/bash /bin/bash 35 1 38:50 00:38:28 R /usr/libexec/qemu-binfmt/aarch64-binfmt-P /lib64/ld-2.17.so /lib64/ld-2.17.so
--verify /usr/bin/true 140 1 1-00:03:13 00:00:00 R ps -e -o pid,ppid,etime,time,state,args [root@83d610f0f031 /]# The same scenario doesn’t happen on our previous build system using Ubuntu 20 (qemu 4.2-3ubuntu6.27 and Docker 24.0.5). I also did the following scenario:
I don’t know for sure this is a QEMU issue but it’s a candidate. Can anyone suggest further paths of investigation? Should I open a QEMU bug? |
