Network PCI do not show

cn flag
SoporteVKT

I'm trying to run a VM on VMware 6.5 with a ubuntu 20.04 and a 10G interface running as a PCI passthrough, but the adapter does not show in command ip a, for example. Reading a bit, I see that card is recognized as a PCI port. I am thanks for your time.

ip a

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
2: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

but the card is shown on the PCI list

Ubuntu 20? So this is a Ubuntu Core 20 server system? ((Ubuntu uses *year.month* for *deb* based products & the *year* format for the *snap* only products; so 20 & 20.04 are different products)

Why do you think that ens192 is *not* your ethernet interface in `ip a`?

I did not know that about Ubuntu, sorry guiverc. It's Ubuntu 20.04 // Chili555. The VM has two network interfaces. ens192 is one that works at 1G and the PCI card works at 10G

Please correct your question (*I can then remove my comment(s) too leaving a more inviting question for potential readers). 20 != 20.04

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
