Okay. Are you using master version?

[potongct]

I installed appvm as of the instructions in https://appvm.readthedocs.io/en/latest/installation.html I used:

nix-env -if https://code.dumpstack.io/tools/appvm/archive/master.tar.gz

to install it and also:

nix-channel --add https://nixos.org/channels/nixos-20.03 nixpkgs nix-channel --update

nix-channel --list home-manager https://github.com/rycee/home-manager/archive/master.tar.gz nixpkgs https://nixos.org/channels/nixos-20.03 appvm --help usage: appvm [] [ ...]

I installed appvm as of the instructions in https://appvm.readthedocs.io/en/latest/installation.html

what's your os?

[potongct]

cat /etc/os-release NAME="Linux Mint" VERSION="20 (Ulyana)" ID=linuxmint ID_LIKE=ubuntu PRETTY_NAME="Linux Mint 20" VERSION_ID="20" HOME_URL="https://www.linuxmint.com/" SUPPORT_URL="https://forums.ubuntu.com/" BUG_REPORT_URL="http://linuxmint-troubleshooting-guide.readthedocs.io/en/latest/" PRIVACY_POLICY_URL="https://www.linuxmint.com/" VERSION_CODENAME=ulyana UBUNTU_CODENAME=focal

Is there any other diagnostics I can retrieve?

[cab404]

Dunno yet) Please, run echo 'remember_owner = 0' | tee -a /etc/libvirt/qemu.conf

[potongct]

echo 'remember_owner = 0' | tee -a /etc/libvirt/qemu.conf tee: /etc/libvirt/qemu.conf: Permission denied remember_owner = 0 ls -al /etc/libvirt/qemu.conf -rw------- 1 root root 32372 Jul 12 09:45 /etc/libvirt/qemu.conf

[cab404]

oof echo 'remember_owner = 0' | sudo tee -a /etc/libvirt/qemu.conf

[potongct]

I ran the following:

echo 'remember_owner = 0' | sudo tee -a /etc/libvirt/qemu.conf remember_owner = 0

and then:

appvm start chromium /nix/store/yfkc2fib1x416ixiqxcb65qinkg2dj6w-nixos-vm 2020/07/15 10:36:31 internal error: process exited while connecting to monitor: 2020-07-15T09:36:30.572294Z qemu-system-x86_64: -blockdev {"node-name":"libvirt-1-format","read-only":false,"cache":{"direct":false,"no-flush":false},"driver":"qcow2","file":"libvirt-1-storage","backing":null}: Could not reopen file: Permission denied

[cab404]

Can you send output of groups?

[potongct]

I believe I may have found the answer.

I had previously set user = 'potong' and group = 'kvm' (potong being my user name).

I reverted user = 'root' and group = 'root' and commented out the now appended remember_owner = 0

Then restarted libvirtd with systemctl restart libvirtd

appvm start chromium /nix/store/yfkc2fib1x416ixiqxcb65qinkg2dj6w-nixos-vm

appvm list Started VM: chromium

I reverted user = 'root' and group = 'root' and commented out the now appended remember_owner = 0

the prolem is that with that everything in ~/appvm is owned by root :(
