- [分享]CentOS in Hyper-V 碰上 hv_vmbus: probe failed for device vmbus_0_11 (-22)
- How can I fine-tune Linux integration components
Windows Server > Windows Server 2008 R2 Hyper-V
My question is related to the Linux integration components version 2. My current environment is MS Hyper-V 2008 hosting a multitude of CentOS VMs (yes, I realize CentOS is not an officially supported distro). The VM I'm seeing this problem with is running CentOS 5.4 kernel 2.6.18-167-11.1.el5 using LVM. When I initially created the machine, I neglected to remove the uneeded SCSI controller at first but subsequently pulled it. I'm not positive it's relevant, but one of the errors is definitely related to STORVSC.
Anyway, I'm not sure whether anyone can assist in debugging this, but here's my dmesg output:
[deadlines@vlad ~]# dmesg | grep ERROR

The Linux IC drivers and modules installed correctly using the setup.pl script, although I did get a warning related to an unused variable. Here's the content of that:
[deadlines@vlad linux_ic]# cat drvinstall.err

The drivers seem to be loading properly for my IDE drive, but these strange probe errors persist during boot. Is there any way to view/modify the list of GUIDs the VMBUS or BLKSVC probes use to enumerate devices?

I just received this responce from one of the team members at Microsoft:
"
Looks like the boot options line in GRUB might be incorrect.
Make sure that you add the following lines to your ‘kernel; line in grub;
Ide0=noprobe ide1=noprobe hda=noprobe hdb=noprobe
And that the blk driver is loaded early in the modules file.
"

Thanks Brian, adding the, "ide0=noprobe" & "ide1=noprobe" options to the kernel fixed the issue for me. The vmbus drivers script adds the, "hda=noprobe" and "hdb=noprobe" commands automatically, but the ide options need to be added manually.

簡單來說，就是在 grub.conf 的 kernel 那一行最後加上
ide0=noprobe ide1=noprobe hda=noprobe hdb=noprobe
就可以解決了！
