Hi, I have some questions about experiments for you please I am building a environment about mpquic between two virtual machines which is host side and VM side when I build the environment completely, and I run the test scripts I found that the vm side can not generate the pcap files and log files I try many times and don't know whats happened the system environment is ubuntu 20.04 arm64 and the kernel is linux 5.4 with mptcp patch here is some pics shows the problem

the first pic is host side, which is the wrong message

the second pic is the vm side, which shows the files after I run the test script

Please use text logs instead of pictures. Given that your output is truncated, I don't know which command you executed, neither on which branch you were. My bet would however be that you are running Python 3 on scripts that were written for Python 2. There might be some parts in the code where the scripts directly write into files, and there are some compatibility issues between Python versions there.

Sorry about that and I will show the text logs then In fact I use both python3 and python2 run the scripts many times and questions are the same so I think questions not occurs in the version of python

the host text log is: python2 quicreqres_tests.py 0_d7.5b10_1_d12.5b10_nt_0_0_loss_0%_nt_1_0_lo 100% 151 353.9KB/s 00:00 siri_quicreqresTest 100% 215 500.7KB/s 00:00 Thread 0 multipath 0 protocol tcp testDirectory siri_quicreqres_20221114_183742_mptcp xpAbsPath /home/parallels/Desktop/minitopo-experiences/experiences/siri_quicreqres_20221114_183742_mptcp/0_d7.5b10_1_d12.5b10_nt_0_0_loss_0%_nt_1_0_loss_0%/0/siri_quicreqresTest topoAbsPath /home/parallels/Desktop/minitopo-experiences/experiences/siri_quicreqres_20221114_183742_mptcp/0_d7.5b10_1_d12.5b10_nt_0_0_loss_0%_nt_1_0_loss_0%/0_d7.5b10_1_d12.5b10_nt_0_0_loss_0%_nt_1_0_loss_0% workingDir /home/parallels/Desktop/minitopo-experiences/experiences/siri_quicreqres_20221114_183742_mptcp/0_d7.5b10_1_d12.5b10_nt_0_0_loss_0%_nt_1_0_loss_0%/0 tmpfs /mnt/tmpfs xpName siri_quicreqres net.mptcp.mptcp_enabled = 0 scp: /mnt/tmpfs/client.pcap: No such file or directory File client.pcap could not be pull from remote server at path /mnt/tmpfs: continue

And then I check the vm side /mnt/tmpfs found that there is not any .pcap file or .log file here I wish you can give me some suggestions to solve the problem thanks again
