The symbol server's client can certainly access the bits through vmchannel.
Ok, that would work i suspect.

Would be nice to have the symbol server in tools/perf/ and also make it easy
to add it to the initrd via a .config switch or so.

That would have basically all of the advantages of being built into the kernel
(availability, configurability, transparency, hackability), while having all
the advantages of a user-space approach as well (flexibility, extensibility,
robustness, ease of maintenance, etc.).
Note, I am not advocating building the vmchannel client into the host
kernel. [...]
Neither am i. What i suggested was a user-space binary/executable built in
tools/perf and put into the initrd.

I'm confused - initrd seems to be guest-side. I was talking about the host side.

For the guest, placing the symbol server in tools/ is reasonable.
