Default password for user virsh

[oz123]

MAAS is adding a user virsh with some password, in addition it enables password based SSH on the VM host. I’d like to know what is that password and If can change it somehow?

@oz123 see https://maas.io/docs/snap/3.1/ui/how-to-manage-vm-hosts#heading--configuration for how to change the password.

I would still like to know where to lookup the password.

@oz123, just FYI. I ended up dumping the DB and looking up the password there.

Is it stored in the DB as clear text password?

@oz123 yes. Here’s the relevant snippet from my dump.

that’s just terrible … this needs to be solved in a better way …
Thanks for sharing the information!

@oz123 just FYI, it’s the same for the passwords it generates for the maas user on BMC/iDRAC/iLO etc.
