你好，

我是安全软件供应商的工程师。我们有一个共同的客户似乎正在经历系统，在其Nutanix雅典卫城平台上使用的VM上挂着。诚然，我对Nutanix并不是很熟悉，因为我主要使用VMware。据报道，这些悬挂在升级我们的安全产品后发生。

VMware具有一个过程，我们可以创建快照文件并将其转换为存储转储文件。这对我们的故障排除工作有帮助，当时您通常无法在VM图像中采取任何措施来强制转储。

我正在尝试找出果酱冠卫卫城是否具有任何可比性的能力。我将建议我们的共同客户也与您联系，但是正在尝试并行构成能力。

欢迎您的帮助和建议。

\nI am an engineer with a security software vendor. We have a mutual customer that seems be experiencing system hangs on their vms in use on their Nutanix Acropolis platform. Admittedly I am not very familar with Nutanix as I mostly work with Vmware. These hangs are reportedly occurring after they upgraded our security product.
\n
\nVmware has a process where we can create snapshot files and convert them into a memory dump file. This is helpful for our troubleshooting effort when normally you cannot take any action within the vm image to force a dump.
\n
\nI am trying to find out if the Nutanix Acropolis infrastraucture has any comparable capability. I will be suggesting that our mutual customer reach out to you as well, but am trying to inverstigate capability in parallel.
\n
\nYour assistance and advisement is welcome.

我会在内部向您询问，因为我不知道，但是您的操作系统在运行什么？

还可以查看KB 3108

您可以尝试配置来宾以在持久磁盘上创建一个转储文件。之后，当客人悬挂时，使用virsh注射nmi向其注入NMI（https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/sect-generic_commands-commands-injecting_nmi.html）。如果访客操作系统是Windows 2012或更晚，则已经为NMI配置了。如果是Linux，我不确定，但是我怀疑必须设置它。

If the guest OS is Windows 2012 or later, it\u2019s configured for NMI already. If it\u2019s Linux, I\u2019m not sure, but I suspect it must be setup.","quoteUsername":"dlink7","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嘿，我知道这已经三岁了，但是我想知道是否有任何更新。具体而言，VMware具有一个流程，可以使您可以从.vmss文件（或我认为我不使用Windows的Windows Systems）从.VMSS文件创建一个VMCORE，而无需手动配置Kdump和panic-on-nmi系统本身，然后让AHV发送NMI。

这是AHV可以做的吗？我不再认为KB 3108是现有的。这对于在可能甚至kdump无法正常工作的问题中捕获来宾VM的情况非常有用，因为您只需将来宾的内存转换为文件，该文件可以由使用KGDB或Crash Utility的内核工程师分析。KVM也可以使用“ Virsh Dump”来做到这一点。

谢谢！

Hey there, I know this is three years old, but I was wondering if there were any updates on this.\u00a0 Specifically, VMWare has a process that allows you to create a vmcore from a .vmss file for Linux systems (or Windows systems I presume, although I do not work with Windows) without having to manually configure kdump and panic-on-nmi on the system itself, and then have AHV send an NMI.<\/p>

\u00a0<\/p>

Is this something AHV can do?\u00a0 I don\u2019t see KB 3108 as existing anymore.\u00a0 This is extremely useful for catching guest VM\u2019s during problems when potentially even kdump can\u2019t work, as you just dump the memory of the guest to a file which can be analyzed by a kernel engineer using kgdb or the crash utility.\u00a0 KVM can do this as well with `virsh dump`.<\/p>

\u00a0<\/p>

Thanks!<\/p>","quoteUsername":"robbmanes","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
