How to view folders from the Mac that hosts the VMWare Fusion guest operating system CentOS or Red Hat Linux?

Solution

  • First, make sure that the VMWare Tools are installed. That always helps.
  • Next, in the WMWare configuration menu of the guest, set up the desired shared folders. There might be already a default shared folder pointing to the user’s home directory.
  • Next, in the guest OS, ls -ld /mnt/hgfs will display the available shared folders.

The AIX NIM server allows a very flexible automated installation process to deploy hundreds or AIX nodes as well as LPARs in a matter of hours. It is possible to achieve similar results using the RHEL kickstart system. This article is about a way of automating the RHEL 5 deployment directly from AIX 6.1 NIM.

Process

  • Copy the RHEL 5 DVD to an NFS file system. E.g. /nfs/rhel5
  • Configure the NIM server to offer the correct boot image in /etc/bootptab:

    rhel-host1.domain.com:bf=/nfs/rhel5/images/netboot.img:ip=xxx.xxx.xxx.xxx:ht=ethernet::sa=xxx.xxx.xxx.yyy:sm=255.255.255.0:
    rhel-host2.domain.com:bf=/nfs/rhel5/images/netboot.img:ip=xxx.xxx.xxx.zzz:ht=ethernet::sa=xxx.xxx.xxx.yyy:sm=255.255.255.0
  • Configure TFTP on the NIM server in /etc/tftpaccess.ctl:

    # NIM access for network boot
    allow:/usr/lpp/sysback/netinst/boot
    allow:/tftpboot
    allow:/nfs/rhel5/images
  • Restart TFTP and reload INETD:

    stopsrc -s tftpd
    startsrc -a -n -s tftpd
    refresh -s inetd
  • Boot the network client with SMS: remote ip setup (with client ip, server ip, router ip, subnet mask, ping test), multiboot setup (with ethernet as first boot device)
  • Follow the regular RHEL install process. (This is where you can get kickstart going.)
  • Reboot the system and reset the boot order.

Error: kernel conflicts with e2fsprogs < 1.37-4

The problem turned out to be the presence of a number if 32bit packages. To solve it, we removed the 32bit architecture packages with:

yum remove *.{i386,i586,i686}

(only do that if you are on x86_64 and you verified that the packages you need are present in 64bit version)
