Subject [jira] [Commented] (CLOUDSTACK-705) IP Address reservation within a network
Date Fri, 22 Feb 2013 10:36:12 GMT


ASF subversion and git services commented on CLOUDSTACK-705:

Commit ea3db2f073a5076d7822497a3032a0cd2d47a297 in branch refs/heads/master from [~saksham]
[;h=ea3db2f ]

CLOUDSTACK-705 IP Address reservation for Isolated Guest Networks

CloudStack uses Guest CIDR for dhcp-range for the Guest VMs. The entire
CIDR is used by CloudStack for assigning IPs to Guest VMs. IP Address
Reservation will allow part of address space to be used fornon CloudStack
hosts/physical servers also, by restricting the address space of CloudStack
Guest VMs. Reservation can be configured using update Network API by specifying
guestvmCidr as an additional parameter. Reservation will be applicable for
Isolated Guest Networks including VPC. reservediprange in the response
will return the IP range that can be used for non Cloudstack hosts.

Tested manually the following scenarios:
Applying reservation when there are running VMs inside the
Applying reservation when there are running VMs outside the
guest_vm_cidr.(not allowed)
Applying reservation when external device like Netscaler is configured
in the guest_cidr.
Applying reservation in VPC tiers.
Applying reservation outside the range of guest_cidr.(not allowed)
