Troubleshooting

Specific XML parsing errors when provisioning a guest automatically

If the deployment function cannot parse the XML file when provisioning a guest automatically, an error message is displayed indicating either a general XML error or a specific XML error.

The following table lists specific XML parsing errors and their descriptions. When trying to resolve specific XML parsing errors, open the XML file in a text editor and search for the listed XML element or attribute name.
Legend for the table:
  • Text that may vary on a per-error-message basis is shown as ??.
  • The XML element names are shown with leading and trailing angle brackets, such as <domain>.
  • The XML attribute values are enclosed within single quotation marks, such as 'type'.
  • The severity levels of the error messages are: error, warning, and informational.
    • Errors cause the deployment to fail immediately.
    • Warnings cause the specified the element or attribute to be ignored, and the parsing of the XML file continues. Certain elements may be missing from the final configuration that causes the guest to behave in unexpected ways.
    • Informationals are for information purposes only and do not affect the deployment of the guest.
Message Severity Cause Possible solution or corrected XML
<disk> missing 'device' attribute Warning The <disk> element must have a 'device' attribute. <disk device='disk'>

<disk device='cdrom'>

<domain> element missing 'type' attribute Error The <domain> element must have a 'type' attribute. <domain type='kvm'>

<graphics autoport='yes'/>

<graphics> 'tlsPort' is not supported, not adding device Warning The <graphics> 'tlsPort' attribute is not supported. Remove any <graphics> 'tlsPort' attributes from the XML file.
<graphics> 'type' attribute missing Warning The <graphics> element is missing the 'type' attribute. <graphics type='spice'/>

<watchdog> element missing 'model' attribute Warning The <watchdog> element is missing the 'model' attribute. <watchdog model='i6300esb'/>
<watchdog> model '??' not supported, not adding hardware Warning The <watchdog> element's 'model' attribute value is unsupported; the only supported value is 'i6300esb'. <watchdog model='i6300esb'/>
No <domain> element Error The outermost element of the XML file is not the <domain> element. Add a <domain> element as the outermost element in the XML file.
No <name> element Error The <name> element is missing from the XML file. Add <name>guest-name</name> to the XML file.
Only one graphic device is supported, using the first device. Warning More than one <graphic> element is defined in the XML file. Remove the extraneous <graphic> elements from the XML file.
Only one video device is supported, using the first device Warning More than one <video> <model> element is defined in the XML file. Remove the extraneous <video> <model> elements from the XML file.
Only one watchdog device is supported, using the first device Warning More than one <watchdog> element is defined in the XML file. Remove the extraneous <watchdog> elements from the XML file.
Unrecognised allocation unit: ?? Error The <memory> 'unit' attribute value is not recognized. See xxx for valid allocation unit identifiers.
unsupported <disk device='??'> attribute Warning The <disk> 'device' attribute value is not 'disk' or 'cdrom'. <disk device='cdrom'>
