COLO state?

[Fabiano Rosas]

Hi COLO maintainers,

Would you please take a look at this issue?

https://gitlab.com/qemu-project/qemu/-/issues/2277

The reporter claims it affects from 9.0-rc2 all the way back to QEMU
7.2. I don't have any kind of setup for COLO, so it will take me a while
to be able to verify this.

Could you also provide clarification on what is the state of COLO these
days? Are any of you looking at it? Do we know of active users of the
feature?

Also, is the MAINTAINERS file reflecting the actual maintenance state
according to you?
