See the docs on -serial telnet in QEMU for a precise description:
http://fabrice.bellard.free.fr/qemu/qemu-doc.html#SEC10
"The telnet protocol is used instead of raw tcp sockets. The options
work the same as if you had specified -serial tcp. The difference is
that the port acts like a telnet server or client using telnet option
negotiation. This will also allow you to send the MAGIC_SYSRQ sequence
if you use a telnet that supports sending the break sequence. Typically
in unix telnet you do it with Control-] and then type "send break"
followed by pressing the enter key."

KVM is part of the QEMU driver so yes. And I already mentioned that I intend
to add it to the Xen driver. Other drivers can use if it applicable - I
imagine the Solaris LDoms driver can use the TCP based syntax for its console
access.
