Problems with RHEL as 4 U4 installing Oracle 10g RAC (VMware Server)

10g RAC has many installation steps and takes a long time. It takes two days to install it.
The following are the problems encountered during installation two days ago:
1. The installation of ocfs2 is delayed for a long time. After installation, run/usr/sbin/ocfs2console and select [clucster]-[configure nodes]. The following error occurs:
"Cocould not start cluster stack. This must be resolved before any ocfs2 ...."

Cause:
1. To Ensure Disable SELinux security! Edit the/etc/SELinux/config file, set SELinux = disabled, and restart the system.
2. The installed ocfs2 package must correspond to the correct kernel version! Uname-R. If 2.6.9-22. elsmp is displayed, it indicates that it is a multi-processor.
Inside like ocfs2-2.6.9-22.ELsmp-1.0.7-1.i686.rpm, with elsmp package!

2. When the clusterware installation Progress reaches 83%, an error is reported suddenly.
Cause: the reason is mainly because of the original situation of VMware, which causes Interruption During remote copy.
1. rm-Rf <CRS install location>/* (delete both nodes)
2. rm-RF/u01/Oracle/orainventory/* (delete both nodes)
3. RM/ocfs/clusterware/OCR/ocfs/clusterware/votingdisk
