@manilx is your nas virtualized on the host, or a separate physical box?

@Seneram ah well excuse my ignorance then, I thought people said the limits were much lower. I can see what you are saying and the big issue with that.

Here's a little test I just ran between VM's over SMB on my Threadripper 7960x build on a Supermicro H13SRA-TF motherboard, def not too bad, these VM's are on different SR's.

ah ok, thanks for the information.

This is pretty minor cleanup question but after removing a NIC, in Xen Orchestra on the host stats page, it still has legend for pifs that don't exist anymore, is there any easy way to clean that up?

@Andrew Thank you Andrew and Olivier, the 4 channel usb card shifted each of its controllers down 2 digits, i removed all the passthroughs, removed the hideback, booted without the card and then re passed the hardware and the box is happy again.

Thanks for the inputs in few threads lately Olivier, appreciate the learning opportunities,

@olivierlambert

I never passed that card to any VMs, there is 2 quadros passed to other VMs and 2 USB channels from a 4 channel card.

Good Evening,

I had some issues with a NIC so I had installed a dual 10GbE Intel X540 PCI-E card, I have since remove all associated networks from VM's and removed the PIF's from the Host.

I ran xe pif-list and confirmed it does not show up there but upon shutdown of the host , remove the card and then power on, it starts to boot, and then shows the normal EFI mapping not available but then instead of showing the splash screen for a second it hangs for a extended period of time and then ends up at a dracut command prompt.

I read the documentation here but this is as far as i can get. (https://xcp-ng.org/docs/networking.html#manage-physical-nics)

The last initqueue message is /dev/disk/by-label/root-yylygk does not exist...starting emergency shell....if I reinstall the card it boots fine.

Thank you, low on sleep and of course you were right...

Hello All.

I just installed a 4 channel USB card, the card has 4 ports each on its own controller so you can split them up for virtualization.

This is what lspci shows:

45:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02)
46:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02)
47:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02)
48:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02)

I first tried this command formatted this way as found on research online, but when the host booted it showed an error in console that it could not parse it

 /opt/xensource/libexec/xen-cmdline --set-dom0 "xen-pciback.hide=(0000:45:00.0)(0000.46.00.0)(0000.47.00.0)(0000.48.00.0)"

I then tried running each separately but it only shows the last one I type in after a reboot running x1 pci-assignable-list

/opt/xensource/libexec/xen-cmdline --set-dom0 "xen-pciback.hide=(0000:46:00.0)"

how do I make all 4 device available to passthru? (i'm running latest 8.3 RC1 with patches)

@Ashkaan you can run xoa alongside your normal configuration if you want to preview it.

@planedrop thank you for the input.

hmm, ok, I did read through that thread, seems like some kind of issue that's existed on every generation so i imagine there is a possibility of a single fix that cures it for everyone.

I checked out Intel's latest workstation stuff and it not interesting or competitive at all with AMD at the moment. (the high end server line is way out of budget)

Thanks for the reponses, I'll keep up on these threads and see what happens and also sounds like maybe it's not a deal breaker to begin with potentially.

I'm currently running a couple Dell r730XD's but looking at modernizing with something a little more tailored to my needs, I only have about a dozen VM's but have some high performance needs (high frequency) on that smaller # of threads than your typical high density setup.

Given that, I'm leaning towards wanting to build a VM host on sTR5 socket AMD 7960x based setup. I've seen some people running threadrippers here successfully but not so much talk about the newer platform, looking for input on if we think this would work or can I not go down this road.

Thank You.

@Gaiking Wow, a little harsh don't you think? If you've been around XCP-NG/XO for any length of time at all you'd know development actually happens at a pretty miraculous pace.

@olivierlambert ah ok, cool, just tried it in XOA and voila. Have a nice weekend.

just updated XO (source) to 4cf03, wanted to check out v6, but when i enter http://10.10.10.42/v6 (usually use RP but wasn't sure if that was a problem so entered IP directly)

I just get a 'Cannot GET /v6'

Before migrating to XCP-NG I was a VMWare user with Veeam as my backup solution, it works but it's 3rd party and somewhat bloated. I think one of the big things xcp-ng has to offer is the native backup. I honestly wouldn't even consider Veeam unless there is some niche use for it that native can't do.
