Buenas
Yo no iria tan rápido y me pensaría lo del driver, ya que tambien afecta al consumo de recursos del esx. No sirve de nada tener el driver de red net3 en un 2003 paravirtualizado cuando todos los demas son lance.
Creo que la solución óptima es nivelar todos los adaptadores. En mi caso hago siempre el intento de que todos los sistemas puedan ver el mas avanzado comun y no en todos los casos es posible usar el scsi paravirtual o el net3.
Te adjunto lo que dice vmware al respecto aqui
Flexible — The Flexible network adapter identifies itself as a Vlance adapter when a virtual machine boots, but initializes itself and functions as either a Vlance or a VMXNET adapter, depending on which driver initializes it. With VMware Tools installed, the VMXNET driver changes the Vlance adapter to the higher performance VMXNET adapter.
E1000 — An emulated version of the Intel 82545EM Gigabit Ethernet NIC. A driver for this NIC is not included with all guest operating systems. Typically Linux versions 2.4.19 and later, Windows XP Professional x64 Edition and later, and Windows Server 2003 (32-bit) and later include the E1000 driver.
VMXNET 2 (Enhanced) — The VMXNET 2 adapter is based on the VMXNET adapter but provides some high-performance features commonly used on modern networks, such as jumbo frames and hardware offloads. This virtual network adapter is available only for some guest operating systems on ESX/ESXi 3.5 and later.
VMXNET 2 is supported only for a limited set of guest operating systems:
o 32 and 64bit versions of Microsoft Windows 2003 (Enterprise and Datacenter Editions).
Note: You can use enhanced VMXNET adapters with other versions of the Microsoft Windows 2003 operating system, but a workaround is required to enable the option in VMware Infrastructure (VI) Client or vSphere Client. See Enabling enhanced vmxnet adapters for Microsoft Windows Server 2003 (1007195) if Enhanced VMXNET is not offered as an option.
o 32bit version of Microsoft Windows XP Professional
o 32 and 64bit versions of Red Hat Enterprise Linux 5.0
o 32 and 64bit versions of SUSE Linux Enterprise Server 10
o 64bit versions of Red Hat Enterprise Linux 4.0
o 64bit versions of Ubuntu Linux
VMXNET 3 — The VMXNET 3 adapter is the next generation of a paravirtualized NIC designed for performance, and is not related to VMXNET or VMXNET 2. It offers all the features available in VMXNET 2, and adds several new features like multiqueue support (also known as Receive Side Scaling in Windows), IPv6 offloads, and MSI/MSI-X interrupt delivery.
VMXNET 3 is supported only for virtual machines version 7 and later, with a limited set of guest operating systems:
o 32 and 64bit versions of Microsoft Windows XP, 2003, and 2008
o 32 and 64bit versions of Red Hat Enterprise Linux 5.0 and later
o 32 and 64bit versions of SUSE Linux Enterprise Server 10 and later
o 32 and 64bit versions of Asianux 3 and later
o 32 and 64bit versions of Debian 4/Ubuntu 7.04 and later
o 32 and 64bit versions of Sun Solaris 10 U4 and later
o 32 and 64bit versions of Ubuntu
En principio la E1000 es la mas aconsejable por encima de 2000 SP4, por debajo solo dejaría flexible (2000 y 9x) o vlance (dos-nt-linux 2.0 y algún 2.2)
Así que, salvo que algun best practices o wp me contradiga, sigo pensando que es mejor nivelar que hacer grandes variaciones
