This allows to notify the guest operating system when the virtual machine is executed with a different configuration (e.g.
Snapshot execution or creation from a template). The guest operating system notices the change, and is then able to react as appropriate by marking its copies of distributed databases as dirty, re-initializing its random number generator, etc.Note that auto-creation only works when done throug API/CLI create or update methods, but not when manually editing the config file.vmstatestorage: Default storage for VM state volumes/files.watchdog: model= ,action=Create a virtual hardware watchdog device. Once enabled (by a guest action), the watchdog must be periodically polled by an agent inside the guest or else the watchdog will reset the guest (or execute the respective action specified).
I'm trying to set up Turnkey Linux's Nextcloud with a WD 10TB drive over USB 3 following this guide:.I can run lsusb from the container and see the WD drive. However, no other command shows any sign of the drive existing in the container (fdisk -l, blkid) with the exception of df -h showing a tmpfs mounted on /dev/bus/usb/002/002 sharing the same available space as the container. When I try to mount that file, I'm told it's write only.Has anyone actually been able to make this work? I spent hours on this last night and almost want to go back to ESXi.I should also add - When viewing the disk on the host, I get this error: Error getting S.M.A.R.T. Data: Exit code: 1 (500).
I'd just like to interject for a moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux.
Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called 'Linux', and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system.
Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called 'Linux' distributions are really distributions of GNU/Linux. Bind mounts are a means to access directories at the Proxmox OS level from within LXC containers. This allows multiple LXC containers to access the same directory.
See.It's simple to setup. Airties wus 300 125 mbps driver download. First, create a permanent mount point for the USB drive in Proxmox.
This is at the OS level like any Linux. The USB drive is mounted permanently when you add an entry in /etc/fstab. Then, you simply need to create a bind mount point within your container.Consider the following example. You have permanently mounted the formatted USB partition as /media/usb1 in the Proxmox OS. You want to access this USB partition as directory /data in container 106.In Proxmox, edit the container config file in /etc/pve/lxc for container 106.
Nano /etc/pve/lxc/106.confand add the following line. Mp0: /media/usb1,mp=/data,shared=1Then restart container 106. There will be a directory /data in the container for the USB partition mounted as /media/usb1 in Proxmox. I'd just like to interject for a moment.

Enables a serial connection to and from a virtual machine's serial port over the network. The Virtual Serial Port Concentrator (vSPC) aggregates traffic from multiple serial ports onto one management console. VSPC behavior is similar to physical serial port concentrators.
Using a vSPC also allows network connections to a virtual machine's serial ports to migrate seamlessly when you use vMotion to migrate the virtual machine. For requirements and steps to configure the Avocent ACS v6000 virtual serial port concentrator, see. Server and Client Connections for Named Pipe and Network Serial PortsYou can select a client or server connection for serial ports. Your selection determines whether the system waits for a connection or initiates it.
Typically, to control a virtual machine over a serial port, you select a server connection. This selection lets you control the connections, which is useful if you connect to the virtual machine only occasionally. To use a serial port for logging, select a client connection.

This selection lets the virtual machine connect to the logging server when the virtual machine starts and to disconnect when it stops.
We are trying to connect two Hyper-V VMs through a serial port. Hyper-V exposes the serial port as a named pipe to the host system, and implements the server end of the named pipe. Consequentially, to connect them, we need to write a named-pipe client which connects to both VMs, and copies the data back and forth. Unfortunately, this application loses data.If we connect two hyperterms, and have them exchange data, the transmission sometimes succeeds, but in many cases, the receiving end reports errors, or the transmission just deadlocks. Likewise, if we use the link to run a kernel debugger, it also seems to hang often.What could be the cause of the data loss? What precautions must be taken when connecting named pipes in such a manner?Edit: We have worked around the problem, using. The COM port of the debuggee continues to be exposed through a named pipe, however, the debugger end talks to kdserv via TCP.
The data loss is not due to the named pipes. It is infact the COM ports (emulated and physical) that may lose data since they operate with a small buffer in the UART.The named pipe receives all the data that is written to the COM port. Your program reads data from the named pipe and writes it to another named pipe.
This is where data loss can originate if you write too fast the receiveing COM port's UART can overflow leading to data loss.You may need to add some delay to avoid exceeding the baud rate expected by the receiving side.In addition, you are missing ResetEvent calls in your program.For your KD issues, you may need to add to the connection string. I think John's suggestion is correct - if u are using a slow CPU to emulate TWO VM, then the guest OS's drivers for serial port is highly drifted away from the high speed version. So John's suggestion is to set the input/output side of the serial link to the slowest possible speed. Ie, you cannot use high baud rate for the inter-VM serial communication. Instead u have to use the slowest possible speed, and so that the VM guest driver will take that cue and use the slower version of the driver. But your physical machine must have sufficient CPU speed to run two VM concurrently, to avoid the 'emulation drift' of the the serial driver.Well, just my guess, but there is a VirtualBox version of your problem, seemingly no issues running it:But the following bug ticket for VirtualBox does describe many similarities to your problem:And reading the end seemingly indicate the solution has to do with VirtualBox's internal source code. Perhaps it is Hyper-V's problem?
