    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;No you will still require VT, RVI etc to run 64bit guests, the remark refers to the hypervisor now being a 64bit peice of software,  this enables the serious boost in Memory capacity for the hosts etc&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If you found this or any other answer useful please consider the use of the Helpful or correct buttons to award points&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Tom Howarth VCP / vExpert&lt;/P&gt;&lt;P&gt;VMware Communities User Moderator&lt;/P&gt;&lt;P&gt;Blog: &lt;A href="http://www.planetvm.net/"&gt;www.planetvm.net&lt;/A&gt;&lt;/P&gt;&lt;P&gt;Contributing author for the upcoming book "VMware Virtual Infrastructure Security: Securing ESX and the Virtual Environment”.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <title>64bit Guests/VT?</title>
      <link>https://communities.vmware.com/t5/ESXi-Discussions/64bit-Guests-VT/m-p/254844#M2251</link>
      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So does this mean you can run 64bit VM's without VT extentions? I dont think so, but then again there isnt much info on this bullet point....... &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt; &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;!http://www.vmware.com/files/images/buttons/new_icon.gif!Bare-metal, 64-bit hypervisor architecture.&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;Achieve near-native virtual machine performance, reliability and&lt;/P&gt;&lt;P&gt;scalability with production-proven hypervisor technology that runs&lt;/P&gt;&lt;P&gt;directly on server hardware, without the need for a host operating&lt;/P&gt;&lt;P&gt;system.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I think that's just referring to the fact that the ESX hypervisor has gone 64-bit. Probably means that you can &lt;STRONG&gt;only&lt;/STRONG&gt; run ESX on 64-bit CPUs, rather than the other way around of being about to run VMs on non-64bit VT processors.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Alex&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;A href="https://communities.vmware.com/www.phdvirtual.com" target="test_blank"&gt;www.phdvirtual.com&lt;/A&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Yep, that's correct, vSphere requires 64bit hardware.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Take a look at this article: &lt;A href="http://searchvmware.techtarget.com/tip/0,289483,sid179_gci1354027_mem1,00.html" target="test_blank"&gt;http://searchvmware.techtarget.com/tip/0,289483,sid179_gci1354027_mem1,00.html&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;=========================================================================&lt;/P&gt;&lt;P&gt;William Lam&lt;/P&gt;&lt;P&gt;VMware vExpert 2009&lt;/P&gt;&lt;P&gt;VMware ESX/ESXi scripts and resources at: &lt;A href="http://engineering.ucsb.edu/~duonglt/vmware/"&gt;&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;A href="http://twitter.com/lamw"&gt;&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;IMG src="http://engineering.ucsb.edu/~duonglt/vmware/vexpert_silver_icon.jpg" /&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If you find this information useful, please award points for "correct" or "helpful".&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;As stated, you won't be able to install ESXi unless you have 64 bit processors.   You will be able to install on Intel CPUs without VT, but you'll just be able to run 32 bit guests.  VT is still required for 64 bit guests.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Does that mean that 64 bit COS ha nothing to do with 54 bit VM's, VMware still depends on Harware ware vendor to install 64 bit vm's??&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Please help me to understan this.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt; &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
