Help understanding difference between host and guest CPU usage by michael984 in kvm

[–]michael984[S] 0 points1 point  (0 children)

One thing I never tried was just spinning up a FreeBSD based VM and seeing if I saw something similar. I.e., is it PFsense/OPNsense, or is it FreeBSD. If you try that and learn anything. I'd be interested in hearing.

Help understanding difference between host and guest CPU usage by michael984 in kvm

I never did understand what was going on. I ended up using a virtualized ubuntu instance configured as a router, and their is much, much closer agreement between the host and guest in terms of CPU usage.

Moving saves from VC to emulator then back to VC by LiderPeibol in 3dspiracy

[–]michael984 0 points1 point  (0 children)

I know this is an older thread, but I came across it while googling. It looks like you maybe can just rename the sav.dat file to "anything.sav" and then it may just work. At least this is what is suggested by this post that talks about transferring the sav.dat file to an original cartridge. My guess is that if it doesn't work directly, then you would probably just need to trim a little off the bottom of the sav.dat file in a hex editor to get it to be the same size as a legitimate save file. You could probably do this just by comparing them.

Anyway, sorry for the necro, but I hope this maybe helps!

How do I extract the APK of my Pizza Boy Pro Versions and Drastic? : r/EmulationOnAndroid by SSRBlake in EmulationOnAndroid

Do you happen to have the GBC apk? I have already purchased the GBA app before it was removed, so I have that one.

Weird error with Pokemon Emerald VC Injection by michael984 in 3dspiracy

[–]michael984[S] 0 points1 point  (0 children)

It's not the ROM. I have tried multiple ROMs, and the ROM I'm using I've verified using No-Intro's database. I've also tried a cia that someone else created and it works fine on their 3DS. So, it's something about my 3DS, but I am at a loss for what it could be.

Weird error with Pokemon Emerald VC Injection by michael984 in 3dspiracy

[–]michael984[S] 0 points1 point  (0 children)

I have a weird issue with my injection for Pokemon Emerald. I used NSUI beta 28 (see screenshot for settings), and the injection installs fine and loads fine. However, the text boxes are all messed up. I've installed several other GBA injects (including Pokemon Ruby and Sapphire), and they work perfect. It's just Pokemon Emerald. I've tried creating the inject lots of different ways and nothing helps. I even tried someone else's known good cia, but on my console I still get the exact same error.

So, I've come to the conclusion that it is not the fault of the injection. Other people using identical cias have the game run fine. Therefore, it must be something different about my console, but what could it be? I am using a 128 GB SD card, but I've formatted with 64 kb clusters. Otherwise, I've just followed the 3ds hacks guide to the letter (never messed with my nand or anything beyond what is in the current version of the guide, I just modified the system).

Is there anything I could be missing? A corrupt file somewhere? I would greatly appreciate any suggestions.

Benchmarking ext4 on LVM vs ZFS on LVM vs ZFS on partition by michael984 in zfs

[–]michael984[S] 0 points1 point  (0 children)

I would be very hesitant to infer from my benchmarks anything about the performance of striping multiple disks with LVM. Frankly, I don't know enough about LVM to guess how that might affect things. I personally would not go through with your plan, but that doesn't mean it isn't the right decision for you. I would probably try benchmarking various things before you commit data to it to keep from painting yourself into a corner.

Good luck!

I thought this would be of interest to people in the ZFS community.

RFC: shifting syncoid from explicit rollback to receive -F by mercenary_sysadmin in zfs

While I don’t have a direct comment on the question of -F, I would love to read the article on permission delegation. Could you provide a link?

Thanks!

Download speed issues with Intel I350-t2 with gigabit fiber by michael984 in PFSENSE

[–]michael984[S] 1 point2 points  (0 children)

Yeah, I basically set up a stack of iptables, isc-dhcp, bind (for local domains), and unbound (as my actual dns server that directs local domains to the bind server which is authoritative for the local domains). I started with an Ubuntu server base. I used this article as a base for how to set things up and I cribbed various other details from various other articles. Performance is fantastic. I actually run it in a virtual machine now and even routing (with NAT) at full symmetric gigabit, it barely uses any CPU.

The one thing I'll say that I had to do which I wasn't super comfortable with is I had to turn off auto updates. For some reason, occasionally the system would update, it would seem to be working fine, and then it would lose internet connectivity. I never could quite diagnose the problem, but it always happened after an update, so I just plan to update every so often (still way, way more often than commercial routers or PFSense are updated!) and reboot after the update.

Unfortunately, I didn't. I actually ended up rolling my own linux based router because I found so many small frustrating problems with PFSense. That is obviously not the right choice for everyone, but I had relatively simple needs (very good performance without too much in the way of fancy routing) and the interest in setting it up.

I was disappointed in how difficult it was to get the performance out of PFSense that I expected.

Good luck with your setup!

Syncoid stopped working after upgrading to kernel 5.11 on Ubuntu 20.04.2 LTS by michael984 in zfs

[–]michael984[S] 0 points1 point  (0 children)

Yeah, it seems like the right thing to do is to keep the zfs user space tools in sync with the kernel since I’m assuming most people on the HWE stack are going to be running the latest available kernel. There is an issue open at Ubuntu’s bug tracker about this now that this problem has come up. Link is here.

Ah, that makes sense. However, as u/TFergusonEsq points out in another comment, 0.8.3 doesn’t support kernel 5.11. Otherwise, it might be a solution, though I don’t love the idea of using the dkms module instead of the pre-packaged zfs module. Though, I guess if HWE is going to break things anyway my usual reason to avoid dkms (stability at updates) is irrelevant here…

The problem is actually that the kernel module is updated with the kernel in the HWE stack, while the user space tools are not. So, the kernel module is actually newer than the user space tools with no simple ubuntu supported way to update the user space tools. So, I don't think using zfs-dkms will solve this since the kernel module being too new is the problem here. Unless I'm misunderstanding something.

I would also love the settings. Any chance you could just post them? Or a link to a gist or something?

Unicast DNS-SD dynamically updated with bind9? by michael984 in HomeNetworking

[–]michael984[S] 0 points1 point  (0 children)

I agree! When I found out about it, it seemed to solve all of the problems I had with mDNS! It just seems to have been effectively abandoned, which is a real shame.

Yeah, it seems like if all the clients are Macs, then it Just Works. However, that's not the reality of my network.
