Errors in dmesg
When adding a an eSata PCI device to my vm configuration (SB700/SB800 Sata Controller AHCI Mode) receive this error: Kernel; journal commit I/O error. This immediately delets the vm machine from the virt-manager and locks up the host. To return to normal a hard, power off, reset is necessary. There is no way a guest configuration should shutdown the host. In inspecting the output of mount, I found my eSata disk mounts to the Fedora host at /dev/sdb1. I then went into vm configuration and added a storage disk for this device and seleted SCSI type. With the eSata disk plugged in at vm startup the vm Windows machine saw this disk and installed the driver automatically. I repeated this process only this time selecting IDE disk and it also worked via the eSata connection. I believe the eSata devices should be plug and play just like USB. If so, how are is eSata to be configured or is this work in progress? dv7-1230us, Fedora standard release with updates as of 7/13. No testing updates.

I can not reproduce this with 2.6.30 builds. (i.e seems fixed in 2.6.30) Paul: Your report seems to be a different issue (not related that MSI breaks eSata) |
