Ccarles89 reacted to IsThisThingOn's post in the thread Whole disk backup every time on stopped VM with
Like.
Like others already said, by default it reads everything. The money quote line is this one: 107: 2026-02-28 21:00:07 INFO: scsi0: dirty-bitmap status: created new Since the VM is not running and/or you have the stop backup mode, it can't make... -
CNo. It is read completely, to seek and find modified chunks. Look at "write: 0 B/s" in every line ;-) In a simplified nutshell: the source is read chunk by chunk. The chunk is hashed. That checksum is sent to the PBS. The PBS notices that a...

Ccarles89 reacted to fba's post in the thread [SOLVED] Another io-error with yellow triangle with Like.
ARC is for a default installation on a PVE 9 with 32 GiB much lower. So the example is missing clear directions and could be phrased much better to be helpful.

Ccarles89 reacted to fargo's post in the thread Recommendations for virtualized Router/Firewall on Proxmox with Like.
Thank you guys for the suggestions. I think I'll install OPNsense and see how things will go.

Ccarles89 reacted to Blueloop's post in the thread Recommendations for virtualized Router/Firewall on Proxmox with Like.
I'll give you some options: OPNSense pfSense VyOS Proxmox! A Debian box is quite capable of being a very decent router and you already have one: Proxmox. However, that is one for the likes of me to run up. What you probably need is something...

Ccarles89 replied to the thread Recommendations for virtualized Router/Firewall on Proxmox.I'd recommend Opnsense. It fits all these requirements and it can be installed as a VM on Proxmox VE (just download the iso-vga installer) https://opnsense.org/ It's basically an open source firewall. Among other functions, you can create...

Ccarles89 reacted to RoCE-geek's post in the thread Redhat VirtIO developers would like to coordinate with Proxmox devs re: "[vioscsi] Reset to device ... system unresponsive" with Like.
The resolving commit for mentioned vioscsi (and viostor) bug was merged 21 Jan 2026 into virtio master (commit cade4cb, corresponding tag mm315). So if the to-be-released version will be tagged as >= mm315, the patch will be there. As of me...

Ccarles89 reacted to bobf's post in the thread Guest firewall letting blocked packets hit guest VM during fail over with Like.
That sounds like a reasonable fix. A minor delay in handoff between the nodes in the interest of security is very much acceptable. I look forward to seeing it pushed out once you get it applied and tested. Thanks!

Ccarles89 reacted to shanreich's post in the thread Guest firewall letting blocked packets hit guest VM during fail over with Like.
understandable, the only mitigation I can currently think of is by utilizing a hook script, but that won't catch every case in the guest lifecycle. I'll look into creating patches that resolve this problem by making the guest wait for a firewall...

Ccarles89 reacted to SteveITS's post in the thread Guest firewall letting blocked packets hit guest VM during fail over with Like.
Interesting, I’d have also expected firewall rules to be applied the whole time. Can access be controlled by a firewall outside Proxmox? At least for external connections… That’s our primary method though we use Proxmox firewall in a few cases...

Ccarles89 reacted to bobf's post in the thread Guest firewall letting blocked packets hit guest VM during fail over with Like.
Just an update. I have confirmed that I can exploit this to establish an SSH session with the guest by simply probing the ssh port every second. As soon as I migrate the VM to another node the session connects and I can use that session as long...

Ccarles89 reacted to Johannes S's post in the thread VMWare to Proxmox Conversion Help - Dell PowerVault ME5224 Integration / Shared Storage Questions with Like.
This is true in theory but not always possible. There is, for example, a well-known enterprise-grade backup software, who allows backing up MS SQL clusters, but doesn't support the backup of MySQL/MariaDB/Oracle or PostgreSQL clusters. For this...

Ccarles89 reacted to LnxBil's post in the thread VMWare to Proxmox Conversion Help - Dell PowerVault ME5224 Integration / Shared Storage Questions with Like.
I would never solve those RPO/RTO demands with a recovery solution, I would always go with internal replication/standby solutions within the database. There is also a reason those techniques exist in those products for decades. So those should be...

Ccarles89 reacted to alexskysilk's post in the thread Best architecture for running 50+ VDSs each with its own Proxmox VE on a large Dedicated Server (2 TB RAM) with Like.
because its dumb. YOU might convolute a way to make it make sense; in my world, customers pay me to AVOID complexity. again, the product is the VM.

Ccarles89 reacted to alexskysilk's post in the thread Best architecture for running 50+ VDSs each with its own Proxmox VE on a large Dedicated Server (2 TB RAM) with Like.
This is how I look at it. You are offering to operate a bus for people. but instead of selling seats, you are putting busses inside your bus. Whats the use case?! If you're trying to offer a customer resources that they can distribute between...

Ccarles89 reacted to alexskysilk's post in the thread Best architecture for running 50+ VDSs each with its own Proxmox VE on a large Dedicated Server (2 TB RAM) with Like.
no. There is almost NEVER a use case for nested hypervisors except for development/lab use. Even if we assume there are no cpu/ram performance degradation that occurs with modern VT extensions (hint: there are) the consequences of cascading...

you use the word "need" in a context I dont understand. This isn't a rational product offering as far as I can tell.

Ccarles89 reacted to alexskysilk's post in the thread Best architecture for running 50+ VDSs each with its own Proxmox VE on a large Dedicated Server (2 TB RAM) with Like.
You dont. I dont understand the use case enough to comment on the wisdom of the solution; please explain what you mean by VDS, and why you want proxmox inside them.

Ccarles89 reacted to ubu's post in the thread A guard rail suggestion to avoid losing everything like I just did. with Like.
If possible (e.g. enough storage available) you should always restore to a new VMID, or create a backup of the broken system before overwriting it. You can never be sure that a backup is valid and restorable until you have sucessfully restored...

CHi, you may be interesed in the following admin guide section for configuring pveproxy: pveproxy - Proxmox VE API Proxy Daemon Of course, a proper firewall setup is still recommended.
