Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: martinmaurer (martinmaurer) Assigned to: Nobody/Anonymous (nobody) Summary: Syslog on Ubuntu 8.10 (amd64) guest filled up with messages Initial Comment: hi all, I am testing several guests on KVM-82, all with qcow2 and IDE disks, one cpu, no virtio involved. On Debian based systems including Ubuntu I got a lot error messages in the syslog and during boot (dmesg). The systems can installed and looks usable in a first run but what are these messages (see attached)? Windows and Centos guests seems not to trigger this, I only got it on several Debian/Ubuntu 64-bit based systems. My host: Debian Etch 64-bit, KVM-82 here is a part of the syslog of the guest: (running ubuntu 8.10 amd64, 2.6.27-9) ____ Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.565214] ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.565219] ata2.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.565219] cdb 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.565220] res 01/60:00:00:00:00/00:00:00:00:00/a0 Emask 0x3 (HSM violation) Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.565223] ata2.00: status: { ERR } Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.565315] ata2: soft resetting link Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.720988] ata2.00: configured for MWDMA2 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.720995] ata2: EH complete Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.721214] ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.721219] ata2.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.721220] cdb 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.721221] res 01/60:00:00:00:00/00:00:00:00:00/a0 Emask 0x3 (HSM violation) Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.721223] ata2.00: status: { ERR } Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.721315] ata2: soft resetting link Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.876984] ata2.00: configured for MWDMA2 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.876993] ata2: EH complete Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.877223] ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.877228] ata2.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.877229] cdb 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.877230] res 01/60:00:00:00:00/00:00:00:00:00/a0 Emask 0x3 (HSM violation) Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.877232] ata2.00: status: { ERR } Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4793.877324] ata2: soft resetting link Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4794.032985] ata2.00: configured for MWDMA2 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4794.032992] ata2: EH complete Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4794.033211] ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4794.033216] ata2.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4794.033217] cdb 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4794.033218] res 01/60:00:00:00:00/00:00:00:00:00/a0 Emask 0x3 (HSM violation) Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4794.033220] ata2.00: status: { ERR } Jan 13 12:47:35 ubuntu-810-amd64 kernel: [ 4794.033311] ata2: soft resetting link ______________ ---------------------------------------------------------------------- >Comment By: Jes Sorensen (jessorensen) Date: 2010-11-26 09:35 Message: Looks like a bug in the IDE emulation code - are you still seeing this with recent version of KVM/QEMU or can we close the bug? Thanks, Jes ---------------------------------------------------------------------- Comment By: martinmaurer (martinmaurer) Date: 2009-01-13 15:23 Message: I did more tests. seemed that ONLY newer ubuntu kernels as guests suffer from this, Debian standard Kernels are working well as guests. I tested with 8.04 and 8.10. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2504388&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
