Windows Server 2019上的Windows Server 2019 Hyper-V Guest虚拟机Hyper-V主机网络性能错误，错误，问题 [英] Windows Server 2019 Hyper-V Guest on Windows Server 2019 Hyper-V Host Networking Performance Error, Bug, Problem

问题描述

b


我作为IT专业人员在工程学院/大学工作，我们在测试中遇到Windows Server 2019和Hyper-V网络问题设置（非产品）。 我们已经彻底尝试了解决我们问题的所有想法，但是b $ b它仍然存在，所以我跳到论坛上找出是否有其他人看到过这个问题。



出于错误重新生成的目的，我们已将设置减少到所需的最低限度。



我们安装了Windows Server Datacenter 2019的vanilla副本在具有1GB网络的通用Dell PowerEdge R740xd机架式服务器上。 然后，我们添加了Hyper-V功能角色，然后在
VM中创建了运行Windows Server Datacenter 2019的VM guest虚拟机（gen2）。



所有VM guest虚拟机设置非常基本：8个vcore，8 GB内存（非动态），100 GB HD。



来宾Hyper-V VHDx文件位于辅助驱动器D上:(不是主要主机OS C：驱动器。）


来宾VM通过标准Hyper-V虚拟交换机连接到公共网络，该虚拟交换机是在已安装Hyper-V角色。 此处没有特殊设置。



我们将100 MB的zip文件复制到VM guest虚拟机服务器2019 OS c：drive，然后共享ZIP所在的文件夹。



问题：



如果我们与Win Server 2019来宾VM共享建立标准网络连接存储ZIP文件的文件夹，然后通过网络将文件解压缩到本地Win10 1709客户端磁盘，解压缩过程非常缓慢，甚至在某些情况下失败并出现错误
。


如果我们将ZIP文件移动到主机hyper-v 2019服务器的C：驱动器，然后执行相同的解压缩过程，它会很快，正常且没有错误。



如果不是解压缩到Win10 1709客户端，我们转移到Windows服务器（任何版本），再次尝试从Win Serv 2019客户虚拟机解压缩它是正常速度（如同很棒）。



我们甚至尝试解压缩到Win7x64客户端（使用SMB 2.1）并发现速度又回归到了因为错误而非常缓慢。



我们发现我们甚至不需要将文件内容解压缩到本地客户端磁盘。 我们可以简单地"测试"网络上的zip文件完整性和完整性测试很慢。



我们的摘要是：



1. 从Win Server 2019 Hyper-V系统上托管的Windows Server 2019来宾VM SMB 3.1.1网络共享解压缩文件导致可怕的性能（甚至错误）IF，并且仅在您尝试解压缩到的客户端是Windows客户端时操作系统（Win7,8,10）。
$


2. 从网络共享解压缩到本地Windows Server操作系统（任何类型）似乎没有此问题。



3. 从Windows Server 2019来宾VM SMB 3.1.1网络共享到客户端PC的ZIP的直接文件副本不显示问题且速度很快。



4。  该问题似乎与ZIP工具在通过SMB共享检索ZIP文件数据时执行的RANDOM SMB IO操作有关。



5. 邮政编码或内容似乎很重要。



6. 如果Windows Server 2019来宾VM托管在Windows Server 2016 Hyper-V主机上，则问题不存在。



更短的构思摘要：



Windows Server 2019 Hyper-V主机，运行同时运行Windows Server 2019的VM guest虚拟机，如果您正在解压缩的客户端（以上）将具有可怕的SMB共享网络UNZIP性能使用SMB共享连接的网络是Windows客户端
操作系统（7,8,10）。 如果您在服务器操作系统（通过网络）上尝试解压缩过程，则该问题不存在。 如果ZIP是从Windows Server 2019 Hyper-V主机共享的，则该问题不存在。



我们发现这个问题非常烦人且头脑很大！



任何人都可以帮助或重新制作错误吗？



谢谢！

Hi,

I work at an engineering college/university as an IT professional where we are having issues with Windows Server 2019 and Hyper-V networking in a test setup (non-prod).  We have exaustively tried about everything we can think of to solve our issue, but it persists so I'm jumping on the forum to find out if anyone else has seen this problem.

For bug re-production purposes we have reduced our setup to the minimum required.

We have installed a vanilla copy of Windows Server Datacenter 2019 on a generic Dell PowerEdge R740xd rack server with 1GB networking.  We then added Hyper-V feature role, and then created a VM guest (gen2) running Windows Server Datacenter 2019 in the VM.

All VM guest settings were very basic: 8 vcore, 8 GB mem (non-dynamic), 100 GB HD.

The guest Hyper-V VHDx file lives on a secondary drive D: (not the primary host OS C: drive).

The guest VM is connected to the public network through the standard Hyper-V virtual switch that was generated when the Hyper-V role was installed.  No special settings here.

We copy a 100 MB zip file to the VM guest server 2019 OS c: drive, and then share the folder that the ZIP is in.

The Problem:

If we make a standard network connection to the Win Server 2019 guest VM share folder where the ZIP file is stored, and then unzip the file, over the network, to a local Win10 1709 client disk, the unzip process is painfully slow, and even fails with errors in some instances.

If we move the ZIP file to the host hyper-v 2019 server's C: drive, and then perform the same unzip process it is fast, and normal without errors.

If instead of unzipping to a Win10 1709 client, we move over to a Windows server (any version), and again try the unzip from the Win Serv 2019 guest VM it is normal speed (as in great).

We even tried unzipping to a Win7x64 client (using SMB 2.1) and found that the speed goes back to being painfully slow with errors.

We found that we don't even need to unzip the file contents to the local client disk.  We can instead simply "test" the zip file integrity over the network and the integrity test is slow.

Our summary is:

1.  Unzipping files from a Windows Server 2019 guest VM SMB 3.1.1 network share hosted on a Win Server 2019 Hyper-V system results in terrible performance (and even errors) IF and only IF the client you are trying to unzip to is a Windows Client OS (Win7,8,10).

2.  Unzipping from the network share to a local Windows Server OS (any kind) does not seem to have this issue.

3.  A straight file copy of the ZIP from the Windows Server 2019 guest VM SMB 3.1.1 network share to a client PC does not show problems and is fast.

4.  The problem seems to be related to the RANDOM SMB IO operations that the ZIP tool is performing in retrieving the ZIP file data over the SMB share.

5.  ZIP size nor contents seem to matter.

6.  If the Windows Server 2019 guest VM is instead hosted on a Windows Server 2016 Hyper-V host, the problem does not exist.

Even shorter consise summary:

A Windows Server 2019 Hyper-V host, running a VM guest that is also running Windows Server 2019 will have terrible SMB share networking UNZIP performance if the client you are unzipping to (over the network using an SMB share connection) is a Windows Client OS (7,8,10).  The problem does not exist if you try the unzip process on a server OS (over the network).  The problem does not exist if the ZIP is shared off of the Windows Server 2019 Hyper-V host.

We find this problem to be very annoying and a great head scratcher!

Can anyone help or re-produce the bug?

Thanks!

推荐答案

此问题似乎是100％可重复的。

This issue seems to be 100% repeatable.

在2019 Hyper-v主机上创建一个vanilla Windows Server 2019 VM（使用Datacenter来匹配上面报告的示例，不确定这是否重要）。 将zip文件放在2019 VM中的任何驱动器/共享上，并尝试直接从Windows客户端操作系统（经过测试的Windows 7和Windows 10 1709和1809）从网络位置
中提取内容，并且解压缩将非常慢，可能会失败。 使用Windows Server 2016作为客户端进行相同的测试没有问题。

Create a vanilla Windows Server 2019 VM on 2019 Hyper-v host (used Datacenter to match the reported above example, not sure if that matters).  place a zip file on any drive/share in the 2019 VM and try to extract the content from the network location directly from a windows client OS (tested Windows 7 and Windows 10 1709 and 1809) and the unzip will be extremely slow and possibly fail.  Doing the same test using windows server 2016 as the client has no issues.
