How reproducible:

100%

Steps to reproduce

1. Prepare a domain XML with poll max="9223372036854775807"

<domain ...>

<iothreads>4</iothreads>

<iothreadids>
    <iothread id="2"/>
    <iothread id="4"/>
    <iothread id="6">
      <poll max="922" grow="222" shrink="222"/>
    </iothread>
    <iothread id="8" thread_pool_min="2147483647" thread_pool_max="2147483647">
      <poll max="9223372036854775807" grow="456" shrink="789"/>
    </iothread>
  </iothreadids>

/<domain>

2. Define and start the domain

➜  ~ virsh define /tmp/rhel.xml
Domain 'rhel-test' defined from /tmp/rhel.xml

➜  ~ virsh start rhel-test     
Domain 'rhel-test' started

3. Validate the live XML by virt-xml-validate

➜  ~ virsh dumpxml rhel-test|virt-xml-validate -
Relax-NG validity error : Extra element iothreadids in interleave
-:1: element domain: Relax-NG validity error : Invalid sequence in interleave
-:1: element domain: Relax-NG validity error : Element domain failed to validate content

fails to validate

Expected results

virt-xml-validate pass

Actual results

As above.

Additional info:

It works when poll max="922"
