[Fedora-xen] xen 3.4.3 SRPM
If anyone wants to test xen 3.4.3, I have put up a source RPM at http://myoung.fedorapeople.org/dom0/src/xen-3.4.3-0.91.fc13.src.rpm Michael Young -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen

I can run HV32WinXP and HV32FC12 and 1 PV64FC12 all at the same time. However, when any combination involves 2 PV64FC12 (kernel version doesn't matter) the host crashes. Running on the -97 dom0 everything works in all combos. Using Xen 3.4.3. Turning off the virt network cards in the PV64FC12 machines makes things go (obviously not much use though). Tried disabling IPV6, firewall stuff etc. etc. Sometimes it would fire up and go but whichever machine is started second gets really long ping times like it's not receiving unless it sends something (if that makes sense). Sooner or later the host crashes. Strangely a PV64FC12 and a PV64FC10 machine coexist happily. It's only when a second PV64FC12 machine starts up.

Just a quick update: Just tried xen-4.0.0-2. Recompile from source on fc12.x86_64. identical behaviour.

Re: [Fedora-xen] xen 3.4.3 SRPM
Another quick update xen-4.0.1-0.1.rc3.fc13.src.rpm just compiled this under fc12. Identical results with this too (i.e. it's probably in the kernel). I have a (silly) idea for the serial console. The wiki page recommends using a phone camera to capture the screen Well my idea is to add an n-millisecond delay every time the output stream in Xen sees a \n. This would delay the screen updates enough for the camera to see them. The n should be configurable on the kernel boot command line. It's set to 0 right now.

Re: [Fedora-xen] xen 3.4.3 SRPM
Hi Pasi, Had a hiccup overnite: The host became unresponsive in a weird way. The time stopped incrementing. Turns out the clock stopped ticking (which I put down to the interrupts being disconnected). Anyway I decided I'd reset the time using 'time -s 10:41:30'. Kaboom, or actually deathly silence. The machine fully stopped dead in its tracks. Just prior to this I connected to the console of one of the 64PV machines which was just running a ping from yesterday. Anyway, 60,000 or so lines of pings went to the console zipping up the screen. Then it was dead. I did a CTRL-C and eventually it returned to the prompt. So I looked at the other 64PV machine, which was also pining, and identical situation. So I reckon, there's some kind of buffer overflow going on when you're not "xm console MACHINE" connected. Once you pass 60,000 lines of text this buffer overflow causes the RTC to hangup somehow. I pressed the reset button, but this time the 2 64PV machines are not logged in. I'll just let it go and see if it keeps going.

Re: [Fedora-xen] xen 3.4.3 SRPM / console problem
Quick update: Added 3 more VMs. Total of 7 now on this "desktop" computer. 3x32PCFC6 1x32HVFC12 1x32HVwinXP-pro 2x64PVFC12 Host is maxed out now. Everything going well when the pings are not running in the 64PVFC12 machines. Will leave it going for another couple of days. Cheers V p.s. FYI Samba4-Alpha12 Active Directory controller is working well on 64PVFC12.

Re: [Fedora-xen] xen 3.4.3 SRPM / console problem
Update: Completely stable with 7 VMs. Hasn't missed a beat for several days now. Will now run the pings again in 2 of 64PV from the virtual consoles (no graphics - and disconnected) and see if the host clock tick dies again.

Re: [Fedora-xen] xen 3.4.3 SRPM / console problem
Host lockup OS is: Linux seanl64.xx.com 2.6.32.14-1.2.107.xendom0.fc12.x86_64 #1 SMP Wed Jun 16 19:26:35 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux xen-4.0.1-0.1.rc3.fc12.x86_64 livelock appears to be related to the network driver interrupt (source: from scanning the news groups). The network LED is flashing continuously, but the system is locked up from the console. We cannot SSH into the box anymore. Could this be related to interrupt priorities (don't know the hardware ins and outs of that). We have a serial captcha of the XEN output!! Here is the suspicious piece: (XEN) MCE: MSR 417 is not MCA MSR (XEN) traps.c:2854: GPF (): 82c4801ae806 -> 82c4801f7cb3 (XEN) vlapic.c:702:d13 Local APIC Write to read-only register 0x30 (XEN) vlapic.c:702:d13 Local APIC Write to read-only register 0x20 (XEN) vlapic.c:702:d13 Local APIC Write to read-only register 0x20 (XEN) irq.c:243: Dom13 PCI link 0 changed 5 -> 0 (XEN) irq.c:243: Dom13 PCI link 1 changed 10 -> 0 (XEN) irq.c:243: Dom13 PCI link 2 changed 11 -> 0 (XEN) irq.c:243: Dom13 PCI link 3 changed 5 -> 0 (XEN) rtc.c:296: HVM RTC: dom 2 skipping 1683748570 seconds (XEN) rtc.c:296: HVM RTC: dom 13 skipping 1683749071 seconds (XEN) rtc.c:296: HVM RTC: dom 2 skipping 86402 seconds (XEN) rtc.c:296: HVM RTC: dom 13 skipping 91586 seconds (XEN) rtc.c:296: HVM RTC: dom 2 skipping 86408 seconds (XEN) rtc.c:296: HVM RTC: dom 13 skipping 92211 seconds (XEN) rtc.c:296: HVM RTC: dom 13 skipping 86456 seconds (XEN) rtc.c:296: HVM RTC: dom 2 skipping 94532 seconds (XEN) rtc.c:296: HVM RTC: dom 2 skipping 86402 seconds (XEN) rtc.c:296: HVM RTC: dom 13 skipping 94742 seconds Note the "skipping 1683748570 seconds" which is more than 53 years.
