sending an encryption request associated to the first targeted host;
in response to the sending, obtaining a security confirmation from the first targeted host, wherein the security confirmation indicates that an encrypted communication channel has been established between the first VM and the first targeted host, wherein the first VM is executing on the first targeted host.
7. The method of claim 1 , wherein identifying the first VM and the first targeted host comprises using the VM metadata and the host metadata.
8. A system, comprising:
a processor;
a data manager, which when executed by the processor performs a method, the method comprising:
obtaining a first VM movement request;
in response to obtaining the first VM movement request:
identifying a first VM of VMs and a first targeted host of hosts associated with the first VM movement request using VM metadata and host metadata, wherein
the VM metadata comprises:
VM identifiers associated with VMs comprising the first VM,
host identifiers associated with hosts currently hosting the VMs,
a list of unsecured VMs of the VMs, and
a hierarchical listing of the VMs specifying nested VMs;
making a first determination that the first targeted host is registered;
in response to making the first determination:
initiating the movement of the first VM to the first targeted host; and
initiating, after the movement of the first VM, encryption of communication between the first VM and the first targeted host.
9. The system of claim 8 , wherein the method further comprising:
obtaining a second VM movement request;
in response to obtaining the second VM movement request:
identifying a second VM of the VMs and a second targeted host of the hosts associated with the second VM movement request;
making a second determination that the second targeted host is not registered; and
in response to making the second determination:
blocking the movement of the second VM to the second targeted host.
10. The system of claim 8 , wherein the first targeted host is registered prior to obtaining the first VM movement request.
11. The system of claim 8 , wherein the method further comprising:
obtaining a host registration request associated with the first targeted host;
in response to obtaining the host registration request:
making, using host metadata, a second determination that the first host 1 s trustworthy; and
in response to the second determination:
generating a certificate associated with the first targeted host using the host metadata; and
sending the certificate to the first targeted host,
wherein the first determination is made, in part, using the certificate.
12. The system of claim 11 , wherein the certificate comprises:
a public key, and
the host metadata.
13. The system of claim 8 , wherein initiating the encryption of the communication between the first VM and the first targeted host comprises:
sending an encryption request associated to the first targeted host;
in response to the sending, obtaining a security confirmation from the first targeted host, wherein the security confirmation indicates that an encrypted communication channel has been established between the first VM and the first targeted host, wherein the first VM is executing on the first targeted host.
14. The system of claim 8 , wherein identifying the first VM and the first targeted host comprises using the VM metadata and the host metadata.
15. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method, the method comprising:
obtaining a first VM movement request;
in response to obtaining the first VM movement request:
identifying a first VM of VMs and a first targeted host of hosts associated with the first VM movement request using VM metadata and host metadata, wherein
the VM metadata comprises:
VM identifiers associated with VMs comprising the first VM,
host identifiers associated with hosts currently hosting the VMs,
a list of unsecured VMs of the VMs, and
a hierarchical listing of the VMs specifying nested VMs;
making a first determination that the first targeted host is registered;
