4.2.1. Startup Issues¶

OVA startup fails¶

Symptoms

With VMware 6.0 and vSphere desktop client, starting Virtual Service Router VM from OVA file fails with the following message:
```
The OVF package is invalid and cannot be deployed.
```

See https://kb.vmware.com/s/article/2151537.

Hints

Use the vSphere HTML5 client (the desktop client is deprecated).
Repackage the OVA file to use SHA1 hashing instead of the latest SHA256 using ovftool available at https://www.vmware.com/support/developer/ovf/.
```
#  ovftool --shaAlgorithm=SHA1 /path/to/original/file.ova /path/to/new/file-sha1.ova
```

SR-IOV problems¶

Symptoms

Starting a VM (with PCI passthrough in its conf) with libvirt fails, yielding:

error: unsupported configuration: host doesn't support passthrough of host PCI devices

Your XML libvirt domain contains something like this:

<hostdev mode='subsystem' type='pci' managed='yes'>
  <source>
    <address domain='0x0000' bus='0x83' slot='0x00' function='0x0'/>
  </source>
</hostdev>

Hints

Your NIC and your motherboard must support SR-IOV, and the Linux kernel must have booted with appropriate options. Enable the Directed I/O parameter in the BIOS, and ensure “intel_iommu=on” is provided in the kernel command line.
