If you're concerned about the risk warning you can get it via web archives here (though it may take a while to load) : <a href="https://web.archive.org/web/20201109025659/https://www.linuxsecrets.com/3417-creating-kvm-virtual-passthrough" rel="nofollow" target="_blank">https://web.archive.org/web/20201109025659/https://www.linuxsecrets.com/3417-creating-kvm-virtual-passthrough</a></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">NB. virt-manager is only a gui/tool for managing VMs under qemu/kvm (linux host as a type 1 hypervisor effectively) whereas VirtualBox is a type 2 hypervisor (running under the host) and gui in one .. so most of your issues with virtualisation are going to be qemu/kvm related rather than virt-manager related. You do get near native performance in your VMs with qemu/kvm though. There are other tools for managing your qemu/kvm VMs - see <a href="https://www.libvirt.org/index.html" rel="nofollow" target="_blank" class="">https://www.libvirt.org/index.html</a></div><div><br></div><div dir="ltr" data-setdir="false"><br></div><div><br></div><div dir="ltr" data-setdir="false"><br></div> </div><div id="ydp95e65b7fyahoo_quoted_6640126081" class="ydp95e65b7fyahoo_quoted"> <div style="font-family:'Helvetica Neue', Helvetica, Arial, sans-serif;font-size:13px;color:#26282a;"> <div> On Thursday, 20 October 2022 at 14:28:47 BST, Mihai Dobrescu <msdobrescu@gmail.com> wrote: </div> <div><br></div> <div><br></div> <div><div id="ydp95e65b7fyiv4176859362"><div><div dir="ltr"><div>H, thanks for the tips. <br clear="none"></div><div>It is a simple selection/option in VirtualBox, a nobrainer selection.</div><div>I'll read the first link, bur the second gives a security warning, so I'll skip.</div><div><br clear="none"></div><div>I wish there is a simple choice in virt-manager UI too.<br clear="none"></div><div><br clear="none"></div><div>Best Regards.<br clear="none"></div></div><br clear="none"><div id="ydp95e65b7fyiv4176859362yqt18335" class="ydp95e65b7fyiv4176859362yqt7429963177"><div class="ydp95e65b7fyiv4176859362gmail_quote"><div dir="ltr" class="ydp95e65b7fyiv4176859362gmail_attr">On Thu, Oct 20, 2022 at 4:05 PM Bob Power <<a shape="rect" href="mailto:b_power@yahoo.com" rel="nofollow" target="_blank">b_power@yahoo.com</a>> wrote:<br clear="none"></div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex;" class="ydp95e65b7fyiv4176859362gmail_quote"><div><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:16px;"><div></div> <div dir="ltr">Not sure this is a virt-manager question: probably more of a general virtual networking question.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Curious: Did you have this in VirtualBox ?</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Anyway, I'd look at <a shape="rect" href="https://virt.kernelnewbies.org/MacVTap" rel="nofollow" target="_blank">MacVTap - Linux Virtualization Wiki</a> <br clear="none"></div><div><br clear="none"></div><div id="ydp95e65b7fyiv4176859362m_-5566385069795163392ydpbae1044eenhancr_card_7049544447" style="max-width:400px;font-family:YahooSans, Helvetica Neue, Segoe UI, Helvetica, Arial, sans-serif;"><a shape="rect" href="https://virt.kernelnewbies.org/MacVTap" style="text-decoration-line:none;text-decoration-style:solid;text-decoration-color:currentcolor;color:rgb(0,0,0);" rel="nofollow" target="_blank" class="enhancr_card_6885235012"><table style="max-width:400px;" class="yahoo-compose-table-card" cellspacing="0" cellpadding="0" border="0"><tbody><tr><td colspan="1" rowspan="1" width="400"><table style="max-width:400px;border-width:1px;border-style:solid;border-color:rgb(224,228,233);border-radius:2px;" class="yahoo-compose-table-card" width="100%" cellspacing="0" cellpadding="0" border="0"><tbody><tr><td colspan="1" rowspan="1"><table style="background-color:rgb(255,255,255);background-repeat:repeat;background-image:none;background-size:auto;width:100%;max-width:400px;border-radius:0px 0px 2px 2px;border-top:1px solid rgb(224,228,233);" class="yahoo-compose-table-card" cellspacing="0" cellpadding="0" border="0"><tbody><tr><td colspan="1" rowspan="1" style="background-color:rgb(255,255,255);padding:16px 0px 16px 12px;vertical-align:top;border-radius:0px 0px 0px 2px;"></td><td colspan="1" rowspan="1" style="vertical-align:middle;padding:12px 24px 16px 12px;width:99%;font-family:YahooSans, Helvetica Neue, Segoe UI, Helvetica, Arial, sans-serif;border-radius:0px 0px 2px;"><h2 style="font-size:14px;line-height:19px;margin:0px 0px 6px;font-family:YahooSans, Helvetica Neue, Segoe UI, Helvetica, Arial, sans-serif;color:rgb(29,34,40);max-width:314px;">MacVTap - Linux Virtualization Wiki</h2><p style="font-size:12px;line-height:16px;margin:0px;color:rgb(151,158,168);"></p></td></tr></tbody></table></td></tr></tbody></table></td></tr></tbody></table></a></div><div><br></div><div id="ydpb44c2b3eenhancr_card_6885235012" class="ydpb44c2b3eyahoo-link-enhancr-card ydpb44c2b3eyahoo-link-enhancr-not-allow-cover ydpb44c2b3eymail-preserve-class ydpb44c2b3eymail-preserve-style" style="max-width:400px;font-family:YahooSans, Helvetica Neue, Segoe UI, Helvetica, Arial, sans-serif" data-url="https://virt.kernelnewbies.org/MacVTap" data-type="YENHANCER" data-size="MEDIUM" contenteditable="false"><a href="https://virt.kernelnewbies.org/MacVTap" style="text-decoration-line: none !important;
