solution for this issue.<br></div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">The issue is the following:</div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">On
our oVirt 4.2 master environments, we create VM's from sealed template
that has only one vNIC attached to the ovirtmgmt network. Sometimes, and
now I am able to fully reproduce it on a specific VM, when I add new
vNIC, it gets allocated with lower PCI slot id, compared to what is
allocated on the default vNIC. For example, original one got slot id:
0xA, and newer one got slot id: 0x3. <br></div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">The
order of slot ID's affects the network 'ethX' naming on the guest OS
(RHEL 7.4). Lower slot ID's gets numbered from 0 to N. The problem is
that if we had configuration for DHCP on 'eth0' and the order is
changed, we can lose connectivity to the host.</div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">Can you please share your opinion on this issue?</div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div style="font-family:verdana,sans-serif" class="gmail_default">Thanks,</div></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div><div><font size="2"><span style="font-family:verdana,sans-serif">Mor Kalfon</span><br></font></div><font size="2"><span style="font-family:verdana,sans-serif">RHV Networking Team<br><span>Red Hat IL-Raanana</span></span></font></div><div><font size="2"><span style="font-family:verdana,sans-serif">Tel: +972-54-6514148</span></font></div><div><font size="2"><span style="font-family:verdana,sans-serif"><br></span></font></div></div></div></div></div></div></div></div></div></div>
