Подключение к VMWare ESXi5.5 клиентом из под Windows XP

Источник

For those that don't have vCenter or want to connect to a stand alone ESXi 5.5 host via the vSphere Client, you'll need to ssh into the ESXi host and modify the following file: /etc/vmware/rhttpproxy/config.xml

Insert the following xml line into the appropriate section:

<vmacore>
        ...
        <ssl>
            ...
            <cipherList>ALL</cipherList>
        ...
        </ssl>
    ...
</vmacore>

After saving your changes restart the service:
/etc/init.d/rhttpproxy restart
