Whenever I transfer 10G+ data to or from guest VM, with rsync or sftp, after a short period it resets the host as if somebody pressed the "reset" button. I tried this on two different guests with the same result. All of my VMs installed on LVM. If I do the same transfer to the host, without involving guest VMs, there is no issue. Problem appears only when doing data transfer to or from guest VM. The only way I can get it to no to reset is to set bandwidth limit on the network interface to 5mb/s. I reinstalled the host, I recreated the guest VMs, I tried sata and virtio devices, Intel and VirtIO network interface. I can create a 500GB file with dd and then copy it with rsync inside the VM. Works great. I wasn't able to find anything relevant in the logs, or maybe I just don't know where to look or what to look for.
