However, until e1000 initialization is complete, including the final configuration of the e1000 IMR (Interrupt Mask Register), any e1000 interrupts, including LSC (link state change) are ignored. This package contains the Linux kernel image for version 4. Proxmox Vs Virtualbox. virtio在虚拟机中,可以通过qemu模拟e1000网卡,这样的经典网卡一般各种客户操作系统都会提供inbox驱动,所以从兼容性上来看,使用类似e1000的模拟网卡是非常一个不错的选择。. I made a following setup to compare a performance of virtio-pci and e1000 drivers: I expected to see much higher throughput in case of virtio-pci compared to e1000, but they performed identically. The VirtIO API is a high performance API written by Rusty Russell which uses virtual I/O. If I change this to virtio, it drops to not even 1MB/s. 6 kernel security and bug fix update.
