We are using direct LUNs with SCSI pass-through in our FC environment to directly provide the services within our VMs direct access to our data with minimal layers in between.
During tests we have seen that although we are using multipath devices with round robin path configuration, only a single path will be used for all of the IOs. Direct LUNs are based on FC multipath devices with SCSI Pass-through (filtered).
If we run IO-tests on the multipath device of the hypervisor, all paths are saturated. If we run the same tests on the same LUNs mapped as direct LUNs with SCSI Pass-through inside a guest VM, we can see that only one HBA-port is actively used (hypervisor will not display IO statistics for the multipath device or the sd-devices it is based on). So it looks like qemu is not really honoring multipath-configuration and actively only using one path or HBA port. Multiple VMs with multiple direct LUNs will also just use the path which is coming from the first HBA port.
Anybody ever experienced this issue/behavior?
Found an issue documented by RedHat which was related to a non-redundant I/O path, but this is marked as fixed and was documented for ovirt/RHV 4.0 - 4.2 / EL 7.3 - 7.6.
If we disable SCSI Pass-through, everything is running as expected (all active paths are used), but the access to the LUN is virtualized which according to documentation has the impact of higher latency, less IOs, etc.
Hello, I use Proxmox 6.2-11. I have a Windows Server 2019 VM that is installed using "raw" format on ZFS ssd. I also have storage drives setup to pass through to the VM directly with virtual-scsi single and formatted with RAID 1 NTFS. I noticed in Windows Server 2019 the storage drives appear as thin provisioned drives so they cannot be defragmented (they are 8TB magnetic drives). Do I have things misconfigured? How can I let the Windows Server 2019 VM see that the drive should be able to be defragmented? I remember back when I used the old virtio that the drives could be defragmented but I don't see that as an option anymore in Proxmox 6.2.
Thanks.
I have a VM for which I wish to pass through several USB HDDs (U. What is the best way to do so? Right now I pass the USB device through. Would it better to pass the drive through to the vm as a scsi device, i.e.:
qm set <VMID> -scsiX /dev/disk/by-id/...
Are there advantages (performance or other) of one over the other?
Hi. I'm following Yuri's Guide to One GPU Passthrough from the wiki.
On the page https://gitlab.com/YuriAlek/vfio/wikis/Use/#windows, it describes steps for installing Windows into your VM. Step 8 is Load driver Red Hat VirtIO SCSI pass-through controller (E:\vioscsi\w10\amd64\vioscsi.inf).
I have seen a few other pass-through guides mention installing drivers when setting up Windows as well.
Now, the problem is, I already have a Windows VM set up and working to my liking. I want to keep using that one. Is there any way to install these drivers onto an already working VM? Or do I need to start over and create a new VM with these drivers?
Apologies if this isn't exactly the best place to ask, I'm thinking an arduino may be optional at this point, but I figured the other hobbyists on here would be able to give me some words of advice, even if I don't end up needing to use an arduino in the end.
What I'm trying to do:
I want to have a microphone on one side of some plexiglass directly output to a speaker on the other side of the plexiglass. (Think like a bank teller window or something). I would also like to be able to rotate a potentiometer to control the loudness of the speaker. When researching this project, most of the youtube videos I'd come across would be related to either the microphone or the speaker and getting those to work, but never exactly what I'm looking for, which is direct pass through.
In terms of hardware, I picked up a Max9814 automatic adjustable gain microphone, a 3 watt, 8 ohm speaker, a set of rotary potentiometers of various resistances, and a LM386 Super Mini Amplifier Board. The thing is, I don't really know if these components are what I need to accomplish this. I also have an arduino nano and a 5v power supply that I'm sure I could rig and code up to accept the audio signal in from the microphone and play out to the speakers, but then I need to put the potentiometer in the path of the speaker circuit to control the volume.
Am I on the right path? Do I need the arduino to accomplish this, or is it possible to do without? I think I need something to translate the signal from the microphone to the speaker. I was thinking the LM386 could do this, but it only has a 3.5mm jack input and I'm not sure how to wire up the microphone to that.

Excerpt discussing her injuries:
>“I got hit so hard in the head, I honestly had no idea what happened,” Fitz told Inside Edition. “When I stood up I was disoriented and my ears were ringing.”
>She said her vision also went black. Fitz ended up in the emergency room with a concussion and a hairline fracture in her cheekbone. She also had swelling and red marks on her face, she said.
>Fitz said her doctor told her that she won’t be able to return to work for three weeks. Fitz said she was also upset about what she said was the reaction to her injury.
Also mentions displeasure with Hornets broadcasters:
>“There was definitely a laugh from the announcers and a comment 'she seems to be OK,' but I took a basketball to the face,” Fitz said.
Some games like Minecraft: Pocket Edition support mouse and keyboard by default and don’t need touch emulation to work with this input method. But BlueStacks doesn’t offer a way not to emulate touch, but just use mouse and keyboard as if it was connected to android device. It results in games like Minecraft: Pocket Edition not playable on BlueStack since you can’t emulate left/right click with touch. Fixing the issues would result in better game compatibility and, if I’m not mistaking, wouldn’t be technically hard to solve.
Hey everyone,
I'm trying to get freenas up and running in hyper-v but I have run into a few issues sadly. First off I am having issues passing disks through to the guest os (freenas) using a SCSI controller. I would use IDE but hyper-v gen 1 limits you to 2 IDE controllers with 2 drives in each controller. I have tried booting into a windows VM using a SCSI controller and that worked fine, it saw all drives. Does anyone know of a workaround for this issue? I'm running out of ideas.
Secondly, if I try to make a gen 2 VM in hyper-v using freenas, the install process goes fine but when I try to boot into the new vm it hangs on a line that says:
"nvme cam probe device init"
then begins to puke to the screen. I stumbled upon this bug while doing some research last night. It seems like this is an issue inside FreeBSD, but I was hoping someone might have a potential workaround for this issue as well.
Thanks!
So to explain, this doesn't happen every time I pass of course, but its gotten to the point where it's the majority of the time.
And of course I know the game modifies the pass if there's an opposing player or some obstacle. This goes beyond that.
So at this point I rarely ever use the Through Pass because of how bad it is, I only use it to go down the line or if someone is WIDE open. So I just use direct short-ish passes and now it seems that a lot of the time I do that, it passes it like a through pass. And this is when I'm even standing completely still.
So if I wanted to pass to someone directly, it might just pass forward instead and oh guess what that's exactly where an opponent is standing. Doesn't even have to move a cm, it's going to him. This happens so much I barely even play the game at this point which is sad because it's fun when I can actually control the damn people and ball.
Considering I use the through pass way less, it's obvious I notice mistakes less, but still if I through pass it, sometimes it'll try to direct pass the ball while there's a player directly in between me and my teammate. So instead of through passing to the side like it normally does so the teammate can run for it, they just boot it at the opponent's knee's.
I want to keep playing, but there's literally nothing I can do to combat this...
Is there a way to directly pass an ethernet connection to a VM?

If it helps, it's Fragile by Yes, and I think it's an older edition (I got it from a thrift shop). It doesn't seem like there are any major effects on the sound overall.
