SmallStack Virtual Machine Hypervisor.
The hypervisor daemon manages virtual machines (VMs). Please read the SmallStack design document to understand the architecture.
The hypervisor provides a web interface on port
6976 which shows a status
page, links to built-in dashboards and access to performance metrics and logs.
If hypervisor is running on host
myhost then the URL of the main
status page is
http://myhost:6976/. An RPC over HTTP interface is also
provided over the same port.
Hypervisor is started at boot time, usually by one of the provided init scripts. The hypervisor process is baby-sat by the init script; if the process dies the init script will re-start it. It may be stopped with the command:
service hypervisor stop
which also kills the baby-sitting init script. It may be started with the comand:
service hypervisor start
There are many command-line flags which may change the behaviour of hypervisor but many have defaults which should be adequate for most deployments. Built-in help is available with the command:
RPC access is restricted using TLS client authentication. Hypervisor expects
a root certificate in the file
/etc/ssl/CA.pem which it trusts to sign
certificates which grant access to methods. It trusts the root certificate in
/etc/ssl/IdentityCA.pem file to sign identity-only certificates.
It also requires a certificate and key which grant it the ability to get
images and objects from an imageserver. These
should be in the files
The vm-control utility may be used to create, modify and destroy VMs.
The hyper-control utility is used to perform administrator tasks on the Hypervisor.
