在使用VMware ESXI5.5 的时候提示内存限制了，在网上找的了解决方案：
如下文：
1. Boot from VMware ESXi 5.5;
2. wait "Welcome to theVMware ESXi 5.5.0 Installation" screen:
3. Press Alt+F1 for enter console and login as 'root' (no password needed);
4. go to:
cd /usr/lib/vmware/weasel/util/
delete? file:
rm upgrade_precheck.pyc;
5. remove readonly flags;
mv upgrade_precheck.py upgrade_precheck.py.def
cp upgrade_precheck.py.def upgrade_precheck.py?
6. set permissions:
chmod 755 upgrade_precheck.py
7. open script in 'vi':
vi upgrade_precheck.py
8. find "MEM_MIN_SIZE", pres "a" (edit mode. "(4 * 1024 - 32)" change to "(2 * 1024 - 32)", pres 'ESC', run command ":wq" (save & exit);
9. look installer PID:
ps -c | grep weasel
10. kill installer (PID = process Nr.):
kill PID
Installer process run automatically (with modified config script).
Continue from "Welcome to theVMware ESXi 5.5.0 Installation"
