Therefore, change the prefix to 00:0c:29 which is the prefix for auto generated MAC addresses anyway. Allow arbitrary MAC addresses to be used and set the checkMACAddress VMX option to false in case the MAC address doesn't fall into any predefined range. * docs/drvesx.html.in: update website accordingly * src/esx/esx_driver.c: set the auto generation prefix to 00:0c:29 * src/esx/esx_vmx.c: fix MAC address range handling and allow arbitrary MAC addresses * tests/vmx2xml*, tests/xml2vmx*: add some basic MAC address range tests --- diff --git a/docs/drvesx.html.in b/docs/drvesx.html.in index b7909ff1e3..44a144f12a 100644 --- a/docs/drvesx.html.in +++ b/docs/drvesx.html.in @@ -16,8 +16,8 @@ SOAP based VMware Virtual Infrastructure API (VI API) to communicate with the - ESX server, like the VMware Virtual Infrastructure Client does.

    MAC addresses

    +

    + VMware has registered two MAC address prefixes for domains: + 00:0c:29 and 00:50:56. These prefixes are + split into ranges for different purposes. +

    + + + + + + + + + + + + + + + + + +
    RangePurpose
    + 00:0c:29:00:00:00 - 00:0c:29:ff:ff:ff + + An ESX server autogenerates MAC addresses from this range if + the VMX file doesn't contain a MAC address when trying to start + a domain. +
    + 00:50:56:00:00:00 - 00:50:56:3f:ff:ff + + MAC addresses from this range can by manually assigned by the + user in the VI client. +
    + 00:50:56:80:00:00 - 00:50:56:bf:ff:ff + + A VI client autogenerates MAC addresses from this range for + newly defined domains. +
    +

    + The VMX files generated by the ESX driver always contain a MAC address, + because libvirt generates a random one if an interface element in the + domain XML file lacks a MAC address. + Since 0.7.6 the ESX driver sets the prefix + for generated MAC addresses to 00:0c:29. Before 0.7.6 + the 00:50:56 prefix was used. Sometimes this resulted in + the generation of out-of-range MAC address that were rejected by the + ESX server. +

    +

    + Also since 0.7.6 every MAC address outside + this ranges can be used. For such MAC addresses the ESX server-side + check is disabled in the VMX file to stop the ESX server from rejecting + out-of-predefined-range MAC addresses. +

    +
