:/sys/fs/cgroup/freezer$ sudo mkdir mycgroup So I have repeated the lab and I am still unable to delete mycgroup. But I was sure this was the answer to my problem since I had not killed the second terminal process.
As I expected, after shutting down and restarting Ubuntu, mycgroup was gone. How do you clean up after this lab? Thanks.

I’ve completed the lab successfully, but now I get this. I’m using the LF pre-built Ubuntu 18.04 on Vmware Workstation 15 Player. But after doing the lab I’m unable to clean up and delete the cgroup that was created. I don't have any plans to actually use either one though, so I haven't spent much time debugging them.Ĥ.Dumb question. I've been able to install a copy of turnkey linux, but the test isos I've tried for Manjaro Architect and Fedora have failed, but I don't think in a useful way here (Manjaro can't see the internet, although I can ping google, so the installer won't proceed, and Fedora is unable to load the ISO). Yep! Intel Virtualization Technology is enabled (although VT for direct IO and Trusted Execution are not - should they be?ģ. I'm using two old Dell Optiplex 980s (i7 processor, 16 GBs ram, 2x 1TB 5400 HD and 1x 256 GB SSD)Ģ. The ISOs that I am using are the server images downloaded from the Ubuntu website, Vmgenid: b2b667f7-9016-47dd-a7c1-da685d0bf269įor the 20.04 version that I haven't been able to install on any attempt: Ide2: local:iso/ubuntu-18.04.4-live-server-amd64.iso,media=cdrom Sure! For the 18.04 version that worked: (Notably, it only worked once - I've tried again with the same settings and it fails during the install)
