Hi Everyone,
I am trying my hands on xen under Solaris SXCE build 113. The machine has
the following configuration:
2 Quad Core Xeon CPUs
16 GB RAM
Solaris SXCE b113
4 disks - 2 mirrors x 2 stripes under ZFS
The problem is that xen HVM is very slow. I am using the following command
to create an Ubuntu 9.0.4 test vm.
virt-install -n test1 -r 2048 --vcpus=2 -f /vdatapool/data/test1.img -s 50
--vnc --hvm --os-type=linux --location=/vsafepool/shared/
Installs/Linux/ubuntu-9.04-desktop-amd64.iso
Based on some random bits found on google, i did hear it to be slow, but did
not expect it to be crawling slow. I am opening the UI through a remote VNC
connection.
Am I missing something here?
Can you guys point me in the right direction?
Regards,
Dot.yet

This is why IMHO HVM guest is only usable with PV drivers. Meaning Ubuntu HVM install will be almost useless for production purposes since AFAIK there''s no PV driver for its default kernel yet. I actually have an Ubuntu HVM (for testing purposes) and I changed its kernel to RHEL 5.3''s kernel-xen (which has built in PV drivers). The performance improvement was HUGE.> Following is the output from zpool''s iostat: > > vdatapool 79.8G 848G 0 135 0 17.0M17MB/s write with 135 writes/s is a lot (well it can be a lot depending on disk).

[Xen-users] Bluescreen after installing gplpv 0.10.0.69
Hi all, I''m setting up Windows 2008 64bit on xen+hvm after windows setup has finished, I installed the drivers with gplpv_fre_wlh_AMD64_0.10.0.69.msi and a) either get an digital signature error, OR when disabling signature checking via Pressing F8 during boot, get b) a Bluescreen with a STOP: 0x00007B error. I have tried - DSEO from http://www.ngohq.com/home.php?page=dseo (gives same bluescreen), - importing james harper''s signature as CA/etc, no change. (windows still does not recognize xenpci.sys as digitally signed) As far as I grasp the idea, the blue screen should be unrelated to the digital-signature issue, since that is temporarily "resolved" by the F8 option to disable signature verification. 0x7B means that windows has some device issues, so the xen drivers do not load despite disabling the digital signature? additionally I have seen, that after installing the drivers, but before reboot, the device manager lists the xenpci.sys driver for the Xen PV PCI device as "not signed" (but the .sys file has Harper''s siganture according to it''s file-properties). Any ideas? regards, Max Pogner _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Bluescreen after installing gplpv 0.10.0.69
Max, I had the same bluescreen 0x7b on reboot after installing the GPLPV (0.10.0.69) drivers onto a Windows 2008 64-bit domU. What fixed it for me was a reboot with the NOGPLPV boot option and then reboot again with the GPLPV drivers enabled. The blue screen did not re-occur since.

Re: [Xen-users] Bluescreen after installing gplpv 0.10.0.69
Hi Matthias,
sadly, nogplpv options does not have any effect in my case (still blue
screen)
with nogplpv option but without disabling digital signatures with F8:
error because of digital signature.
(it''s "bcdedit /copy {oldid} /d" name and
"bcdedit /set {newid} loadoptions nogplpv" right?)
with nogplpv and with disabled digital signatures: blue screen
STOP: 0x7B
did you use a file, or a real partition (maybe an lvm-volume)?
I am using
disk = [ ''file:/path/to/hda.img,hda,w'' ]
regards,
Max
