This page answers some of the most commonly asked questions about the UOCloud service. If you have any additional questions beyond what you see here, please open a ticket at https://service.uoregon.edu/TDClient/Requests/ServiceDet?ID=18712.

This is currently written for VMware vSphere 6.0.

How do I access the vSphere / VirtualCenter console?

You can access the vSphere Web Client via https://vcenter-1.uoregon.edu/vsphere-client/.

Supported Browsers:

  • Windows
    • IE 10.0.19 and later
    • Firefox 34 and later
    • Google Chrome 39 and later
  • OS X
    • Firefox 34 and later
    • Google Chrome 39 and later
  • In addition the vSphere Web Client requires Adobe Flash Player 16 or later.

For either client you must be on UOnet or connected via UO VPN to connect.

Log in with your Active Directory credentials. If you don’t know what your Active Directory credentials are, try ‘ad\duckid’ and your DuckID password. Replace ‘duckid’ with your DuckID username.

I recieved an email telling me to update 'VMware Tools'. How do I do that?

For more information regarding the tools and how to update them, see: Installing VMware Tools

Can I rename my VM and repurpose it?

Rather than repurposing a VM, we ask that instead you allow us to provision a new VM for you. This way, the VM's purpose, specs, name, and location are better represented in the management console, and allow us to better support you if you have any questions or concerns.

Please request a new VM by filling out our intake form, found here: VMware Intake Form

What does networking look like for Virtual Machines?

Virtual machines are provisioned with a single IP on VLAN104, and a DNS record corresponding to the requested host name. Names for AD-joined Windows VMs must meet the requirements set forth in the UO AD Administrator Guide.  

Additional IPs or DNS records may be added upon request. Please open a ticket.

Subnets available within the Computing Center (CC) or Oregon Hall (OH) datacenters may also be used.  However, this is a limited pool of subnets.  Please contact nethelp@ithelp.uoregon.edu if you wish to request more information regarding networking within the datacenters.

Will my Virtual Machine be protected by a firewall?

VMs are protected by a default deny-all firewall.  Rule changes can be requested at nethelp@ithelp.uoregon.edu. We also highly recomend to keep using the host firewall built in to your OS (iptables, Windows Firewall, etc).

How do I mount .iso files?

Due to the deprecation of NPAPI in modern browsers, mounting local ISO images onto a virtual machine in the VMWare web client is no longer an option.

As a workaround, you can use a datastore to mount ISOs to your VM. Connect to the University’s datastore by selecting the icon beside the CD/DVD drive and choosing the “connect to CD/DVD image on a datastore” option. You should see the “iso” datastore.  There is limited space so be courteous of others and remove your ISOs when you are done.

Is my Virtual Machine backed up?

We are not taking block-level backups of VMs at this time. You should use traditional backup strategies to provide disaster recovery restoration of your host.

Are VM level snapshots available?

Yes we allow limited VM snapshots of hosted machines.  The space used by the snapshot is added in addition to the allocated space of any virtual disks.  Snapshots can be managed via the vSphere clients.  Please follow these guidelines for responsible snapshot usage:

  • No snapshot should be retained for longer than 24 hours.  VMware snapshots are unaligned and cause an unreasonable extra load on the shared storage systems.  This limited retention period also prevents them from growing large and causing issues when making changes to the original disk.  Snapshots older than 24 hours will be automatically deleted.
  • Several snapshots in a chain and/or snapshots large in size will impede virtual machine and host performance due to the additional resources required to commit changes to the snapshots.
  • Special care should be taken when using snapshots on high-transaction virtual machines such as email or database servers. Since snapshots catalog every change to the VM, these snapshots quickly grow in size and fill datastore space.
  • A snapshot file is only a change log of the original and should not be relied upon as a backup solution. Please do not schedule re-occurring tasks that create snapshots on a regular basis. 

If your intented use doesn't fit into these guidelines, please contact us and we will be happy to work with you to find a good solution.  They are many options available.

How is service related information communicated?

A mailing list (isvmwareannounce) has been created to allow people the ability to control their access to this information.  For more information on how to get access, please see: https://lists.uoregon.edu/mailman/listinfo/isvmwareannounce

Is this environment compliant with PCI and/or HIPAA standards?

We will be happy to fulfill any VM request made by the UO community. Please be aware, however, that the UOCloud service has not made any attempt to meet the requirements that are mandated by the PCI and HIPAA standards, and it is unlikely that any plans will be made to do so.
