Hannes Mehnert c7b468fe09 new command: get which downloads a unikernel and dumps it into a file 2020-07-05 21:27:44 +02:00
Hannes Mehnert 5adc2f0a8a vmm_asn: instead of potentially losing information, be honest and fail if requested to encode older versions of unikernel configuration 2020-07-05 20:53:57 +02:00
Hannes Mehnert 125711ac6d further rng cleanups (remove deps from dune); albatross-client-inspect-dump which reads a state file (for cautious upgrades) 2020-07-05 20:39:29 +02:00
Hannes Mehnert 604f3ec52e Bos.OS.Cmd.run_out needs to check the exit status (using Bos.OS.Cmd.success) 2020-05-11 13:26:35 +02:00
Hannes Mehnert 7cad9bd08d on linux, be a bit smarter which network device name to use 2020-04-25 19:59:19 +02:00
Hannes Mehnert 0c5af23848 vmmd: unikernel_info no longer transfers the unikernel image 
regression introduced in dfd22be62b
(which prepared dumping to a file, and restart-on-failure)
this is not desired from a bandwidth point of view, if it is
considered to be a useful feature, there should be a separate
command for it

Hannes Mehnert b7747a2547 linux tap device discovery: redirect stderr of run to /dev/null 2020-04-21 11:07:57 +02:00
Hannes Mehnert 03c9948526 avoid brctl on Linux, use ip instead 2020-04-09 17:02:17 +02:00
Hannes Mehnert be83686a22 Vmm_unix: fix ip tuntap command (provide tap name earlier), also set link up 2020-04-03 17:44:21 +02:00
Hannes Mehnert 65693ea188 revise the "--net=yyy" argument to (optionally) contain a service:bridge 
it used to only contain service, and used the same string for the bridge. This
is not flexible enough to run off-the-shelf unikernels (configured for bridge
"service" and "management" on multi-homed servers). The old behaviour is the
new default (i.e. "--net=service" creates and attaches a tap device to bridge
"service", and passes "--net:service=tapYY" to the solo5 tender). But it is more
flexible now: "--net=service:other-bridge" will create a tap device attached to
"other-bridge" and pass "--net:service=tapYY" to the tender. This way, there's
no need to match bridge names on the actual server with network device names of
the unikernels.

NB: this is (mostly) backwards-compatible: the on-disk data structures are
versioned (and the version is bumped with this PR), an old albatross client can
send "create" commands to a new server. But a new client will get a parse error
from an old server - which is fine taking into consideration the deployment
base.

Hannes Mehnert 55d7fd38ac vmm_ring: unused variable 2019-01-27 22:22:57 +01:00
Hannes Mehnert a9c32d7801 vmmd: actually, first check resources, then exec VM, then insert VM 
in case the insertion fails, raise Invalid_argument

this leads to more sane failure behaviour, and also cleans up resources in case
 vmm_resources.insert_vm fails (or cpuset/open of the fifo, create_process)

Hannes Mehnert 943ea45e25 vmm_vmmd, vmm_unix: compute device name (/dev/vmm/solo5-PID) in vmm_unix (depending on host OS); also destroy this device on shutdown (used to be done by solo5-hvt, but that now drops privileges and is no longer able to do this) 2019-01-20 23:02:01 +01:00
