VMware Fusion 10 – Cannot import .ova virtual appliance templates anymore?

I came across this situation after upgraded Fusion 8 on macOS from to version 10 and didn’t manage to import anymore some particular .ova virtual appliance tempalates in to it. e.g. Citrix XenMobile virtual appliance.

VMware Fusion 10 fails to import .ova template and gives an error: “Invalid target disk adapter type: pvscsi”. Apperantly latest OVF Tool included in it has a bug to import if SCSI Controller type configured in template as “VirtualSCSI” = pvscsi.

Workaround, before VMware fixes this issue, extract .ova template and change the SCSI Controller configured in .ovf file from “VirtualSCSI” SCSI Controller
to “lsilogic”.

Workaround

1. Extract .ova file and you’ll get three files;

– opt.mf
– opt.ovf
– opt.vmdk

2. Open opt.ovf file and edit SCSI Controller section in it from “pvscsi” to “lsilogic”;

<Item>
<rasd:Address>0</rasd:Address>
<rasd:Description>SCSI Controller</rasd:Description>
<rasd:ElementName>scsi0</rasd:ElementName>
<rasd:InstanceID>3</rasd:InstanceID>
<rasd:ResourceSubType>lsilogic</rasd:ResourceSubType>
<rasd:ResourceType>6</rasd:ResourceType>
</Item>

3. After file edited you still cannot import it as the manifest file “opt.mf”, which has been SHA signed, doesn’t match anymore to the original opt.ovf file signed.

4. Use OpenSSL to sign manifest file again (download and install OpenSLL first);

– Openssl sha1 *.vmdk *.ovf > opt.mf

5. After signed manifest file again you’re good to go and import .ova template succesfully. Of course it now uses different SCSI Controller, but it works at least for the latest Citrix XenMobile .ova template.

NetScaler Gateway – Two-Factor Authentication – How to hide 2nd password field

Some two-factor products (e.g. DUO, SMS Passcode) require you to hide the 2nd password field. Easiest way is to use Rewrite policies, which works both Web browser and Receiver self-service.

Tested with:

Citrix Receiver for Windows 4.6.0
Citrix Receiver for Mac 12.4.0
NetScaler 11.1 51.26.nc

If you have any file level customizations on NetScaler, it needs to be reset as per default settings before doing these Rewrite policy – modifications.

For Web browser:

1. Create a Rewrite Action

Type: INSERT_HTTP_HEADER
Header Name: Set-Cookie
Expression: (“pwcount=”+ 1″)

2. Create a Rewrite Policy

Action: Select the rewrite action which you created
Undefined Result Action: -Global undefined result action
Expression: HTTP.REQ.HEADER(“Set-Cookie”).CONTAINS(“pwcount”).NOT

Bind this policy to the Netscaler Gateway Virtual Server where 2FA is configured.

For Receiver Self-Service:

1. Create a Rewrite Action

Type: INSERT_AFTER_ALL
Expression to choose target location: http.res.body(1024)
Expression: “rn”+”<META http-equiv=”X-Citrix-AM-GatewayAuthType” content=”SMS”>”
Pattern: content=”text/html; charset=UTF-8″>

2. Create a Rewrite Policy

Action: Select the Rewrite action which you created
Undefined Result Action: -Global undefined result action
Expression: http.req.url.path.endswith(“vpn/index.html”)

Bind this policy to the Netscaler Gateway Virtual Server where 2FA is configured.
