ESXi 6.0 Update 1 Breaks Horizon View prior to 6.2

ESXi 6.0 Update 1 Breaks Horizon View prior to 6.2


Whilst out on a customer site, I had an unusual error in Horizon View 6.11. One of the pools just had “ViewCompsoer Fault:” and failed all compose jobs. Looking at the VMs in the Admin console, they all showed up as Deleting (Missing). The VMs in the vCenter didn’t exist so I had to manually delete them from the Adam Database using the VMware KBs

After trawling through the SQL Composer database to remove the Composer database entries I started to look at the error logs for View Composer. In Composer the logs had errors relating to failing to initialize the disks as it couldn’t find the path of the cloned disk. After checking the UFA logs in the View Composer log bundle, I came across an error “sslv3 Handshake Alert Error”. After a bit of digging I came across this article from VMware.

So it appears ESXi 6.0 Update 1 disables SSLv3 which is how the View Composer connects to the hosts in all versions of Horizon View prior to 6.2. Installing this update will cause the View Composer to fail on recompose tasks. This was disabled due to a vulnerability but you can re enable this as a workaround, you only need to re-enable port 902 as I have described below. . )

Note: to edit a file in ESXI you can use the command VI in front of the file name, to insert text once in the editor, press the insert ley on the keyboard, once finished editing press escape to exit from insert mode, then type :wqto save and exit, to save without exiting instead use :q!

  1. Create a backup copy of the /etc/vmware/config file
  2. Edit the /etc/vmware/config file to append the following line at the end of the file:

    vmauthd.ssl.noSSLv3 = false

    Note: If you have the line vmauthd.ssl.noSSLv3 = true in the file, change it to vmauthd.ssl.noSSLv3 = false

    For Example:

    [root@w1-fiqabj-003:~] cat /etc/vmware/config
    libdir = "/usr/lib/VMware"
    authd.proxy.nfc = "vmware-hostd:ha-nfc"
    authd.proxy.nfcssl = "vmware-hostd:ha-nfcssl"
    authd.proxy.vpxa-nfcssl = "vmware-vpxa:vpxa-nfcssl"
    authd.proxy.vpxa-nfc = "vmware-vpxa:vpxa-nfc"
    authd.fullpath = "/sbin/authd"
    vmauthd.ssl.noSSLv3 = false
  3. Restart the rhttpproxy service with the command:

    /etc/init.d/rhttpproxy restart

The fix from VMware is to upgrade to Horizon View 6.2 which no longer uses SSLv3
