I need to access guest vms even if they are out of network: some tests
in my environment should be processed without network or with only one
NIC that have private IP and I can't use it remotely.
I need to send system commands, upload files, watch activities, collect
data (that all for software automation)
As there is no "client API" like VIX, I tried to workaround it via
emulated serial.
I enabled emulated serial on each vm like this:
xe vm-shutdown force=true uuid=XXXXXXXX
xe vm-param-remove param-name=other-config param-key=hvm_serial
uuid=XXXXXXXX
xe vm-param-set uuid=XXXXXX other-config:hvm_serial=" tcp:XXXXXXX:YYYY"
xe vm-start uuid=XXXXXXXXX
On guest machine (HVM, Lin and Win) there is perl terminal client to
receive and send data back. All ok, I can manage guest machine and send
files. But there are some issues:
1) If TCP client is down when guest VM is started, there is no way to
reconnect again. The only way is to reboot guest or suspend/resume it.
Also if connection lost during work it is also need to reboot guest.
Is there any way to restart this service somehow?
2) If I send data in one peace guest stops receiving data after 4096
bytes. Guest VM should send at least one byte back and it can receive
data again.
Is it ok or it can be set up somewhere?
